Before introducing the quantitative assessment method for global stability of surrounding rocks of underground caverns according to the present application, the background content involved in the present application is firstly introduced.
The quantitative assessment method and apparatus for global stability of surrounding rocks of underground caverns and the computer-readable storage medium can provide a concrete, practical and effective quantitative assessment solution for the global stability of surrounding rocks of underground caverns.
An execution subject of the quantitative assessment method for the global stability of surrounding rocks of underground caverns mentioned in the present application may be the quantitative assessment apparatus for the global stability of surrounding rocks of underground caverns, or different types of quantitative assessment devices for the global stability of surrounding rocks of underground caverns, such as servers, physical hosts or User Equipment (UE) integrated with such a quantitative assessment apparatus for the global stability of surrounding rocks of underground caverns. The quantitative assessment apparatus for the global stability of surrounding rocks of underground caverns may be implemented by hardware or software, and the UE may be a terminal device such as a smart phone, a tablet computer, a notebook computer, a desktop computer, or a Personal Digital Assistant (PDA). The quantitative assessment and processing device for the global stability of surrounding rocks of underground caverns may be set using a device cluster.
Next, the quantitative assessment method for the global stability of surrounding rocks of underground caverns according to the present application is introduced firstly.
Firstly, referring to
S101, after determining an assessment task for the global stability of the surrounding rock of a target underground cavern, initial data of the target underground cavern are extracted.
It can be understood that the assessment for the global stability of the surrounding rock of the target underground cavern of the present application is based on small-unit cavern units or cavern sections of the target underground cavern. Under this principle, after the assessment task for the global stability of the surrounding rock of the target underground cavern is triggered, the current assessment object, that is, the target underground cavern can be divided into different independent cavern units or cavern sections under a preset similar judgment standard at an early stage of task execution, and these cavern units or cavern sections are used as assessment objects of the global stability of the surrounding rock.
The division of the target underground cavern is based on the initial data, and the initial data is easy to understand, is preliminary data of the target underground cavern when the task for the global stability of the surrounding rock is initiated and provides data basis for subsequent division.
It should be noted that the initial data may be directly carried in task data, or extracted from local or other devices storing the data.
S102, the target underground cavern is divided into different independent cavern units or cavern sections according to the initial data.
In the division processing of the target underground cavern, the principle of similarity is followed, and the cavern units or cavern sections with similar properties on an engineering geological unit are divided into different independent cavern units or cavern sections.
As a practical implementation, in the present application, the division of the target underground cavern may specifically include:
according to geological structures, rock mass structure types, lithology, initial maximum principal stress values, buried depths, included angles between initial maximum principal stress directions and a cavern axis, dimensions, a cavern axis orientation and use functions of different positions carried in the initial data, dividing different positions of the target underground cavern into different independent cavern units or cavern sections within a preset similar judgment range.
Specifically, it may also be understood in combination with the following Table 1:
Table 1—Division table of cavern units or cave sections for global stability assessment of surrounding rocks
It can also be seen from the above Table 1 that the geological structure, the rock mass structure type, and the lithology mentioned above belong to the category of “stratigraphic lithology and structure”;
the initial maximum principal stress value, the buried depth, and the included angle between the initial maximum principal stress direction and the cavern axis belong to the category of “initial ground stress”; and
the dimension, the cavern axis orientation, and the use functions belong to the category of “cavern scale and layout”.
In addition to classifying the categories of influencing factors, in practical application, a similar judgment range suitable for each category may also be configured.
S103, according to a preset stability assessment strategy, the eight factors influencing the global stability of surrounding rocks of the cavern units or cavern sections are rated respectively, as the global stability assessment result of the target underground cavern.
After it is determined that the target underground cavern will be divided into multiple cavern units or cavern sections, these cavern units or cavern sections may be independently subjected to assessment processing for the global stability of the surrounding rock.
It can be understood that the assessment strategy involved in the stability assessment processing here may be pre-configured with corresponding assessment content according to the assessment requirements in practical application.
As another practical implementation, in the present application, the preset stability assessment strategy may specifically rate from eight aspects (influencing factors): a basic quality index of the surrounding rock, an uniaxial compressive strength of the surrounding rock, a local stability condition of the surrounding rock, a relaxation/damage condition of the surrounding rock, a combined relationship between the initial maximum principal stress direction of the surrounding rock and the cavern axis, a combined relationship between a main structural plane and the cavern axis, groundwater and other influencing factors.
Specifically, it may also be understood in combination with the following Table 2:
Table 2—Rating table of eight influencing factors for global stability of surrounding rocks
It may also be seen from above Table 2 that the stability assessment involved in the present application may also be specifically performed in the form of a rating, and the assessment result is reflected within ratings.
Furthermore, for the local stability condition of the surrounding rock of one influencing factor (one of the eight influencing factors) mentioned above, in practical application, the present application may specifically evaluate from four aspects: a local deformation stability of the surrounding rock, a block stability of the surrounding rock, a collapse tendency of the surrounding rock and a rockburst tendency of the surrounding rock. For the respectively corresponding assessment processing, please refer to the following Tables 3-6:
Table 3—Local deformation stability classification of surrounding rocks
Table 4—Block stability classification of surrounding rocks
Table 5—Collapse tendency of surrounding rocks
Table 6—Rockburst tendency of surrounding rocks
The local stability rating of the surrounding rock of the same unit or cavern section of a single failure type may take the lowest value of all ratings of this type, and the local stability rating of the surrounding rock of the same unit or cavern section may take the rating corresponding to the most unfavorable type of each failure type.
For a single cavern unit or cavern section, after eight influencing factors are rated by the preset stability assessment strategy, the ratings of eight influencing factors may also be accumulated, and the accumulated ratings are confirmed as the global stability assessment results of the surrounding rock of respective cavern units or cavern sections, as the global stability assessment result of the target underground cavern.
As an example, corresponding to the eight influencing factors mentioned above, the corresponding local stability rating may be calculated in combination with the following formula:
wherein S is the global stability rating of the surrounding rock of the underground cavern, and Si (1=1-8) is the rating of each influencing factor of the global stability of the surrounding rock of the underground cavern.
In addition, it is easy to understand that, in practical application, corresponding weight values may also be configured for eight influencing factors involved in the stability assessment process, to finally obtain the global stability ratings of the surrounding rock of different cavern units or sections.
Of course, for different influencing factors or even different cavern units or cavern sections involved in the stability assessment process, in practical application, different adaptation strategies and inclination strategies may also be configured according to different requirements, so that the global stability ratings of the surrounding rock of different cavern units or cavern sections can be finally obtained, and more accurate determination and presentation effects can be obtained according to actual situations.
In addition, the stability assessment result based on the ratings may also include other contents, to better indicate specific stability degrees, and the stability degrees may be divided according to the specific ratings.
For example, as yet another practical implementation, the process of obtaining the stability assessment result based on the ratings may specifically include:
accumulating ratings of the eight influencing factors;
determining, based on the preset global stability classifications of the surrounding rock of the underground cavern and rating ranges thereof, a target global stability classification corresponding to the accumulated rating, the global stability classifications of the surrounding rock of the underground cavern is divided into four classifications: stable, basically stable, understable and unstable respectively; and
confirming the accumulated ratings and the target global stability classifications as the global stability assessment results of the surrounding rock of respective cavern units or cavern sections, as the global stability assessment result of the target underground cavern.
It can be understood that under this setting, in addition to the basic ratings (accumulated ratings), the global stability classifications are also introduced, so that the specific stability degree of the target underground cavern can be indicated in combination with the ratings and the global stability classifications in an intuitive and concrete presentation way.
As yet another example, in the practical application of the present application, the highest value of the global stability rating of the surrounding rock of the underground cavern may be 100, and the lowest value may be 0.
In addition, the upper and lower limits of the rating interval corresponding to the global stability classification of the surrounding rock of the underground cavern are up to the nearest multiple of 10 based on the sum of the upper and lower limits of the rating interval of each influencing factor.
Specifically, please refer to the following Table 7.
Table 7—Global stability classifications of surrounding rocks
In addition, for the above content, for defined ranges involved by the cavern units or cavern sections, or the rating ranges (corresponding to the stability assessment strategy) involved in rating, in yet another practical implementation, the corresponding ranges may also be set according to two different stages, that is, a survey and design stage and a construction stage. Therefore, in practical application, the stability assessment processing performed in the present application can be accurately adapted to the survey and design stage and the construction stage, thereby avoiding the problem of different assessment results for the global stability of the surrounding rock caused by different survey depths and detection depths of engineering geological conditions in different stages, and possible changes of an excavation and support design solution.
Specifically, the above content (including respective exemplary implementations) may also be understood in combination with a scenario schematic diagram of the quantitative assessment method for the global stability of surrounding rocks of underground caverns in the present application shown in
Generally speaking, it can be seen from the above content that, for the assessment of the global stability of surrounding rocks of underground caverns, the present application firstly divides the target underground cavern to be subjected to stability assessment into different independent cavern units or cavern sections according to the initial data, and carries out multi-factor assessment processing on the global stability of the surrounding rock of these cavern units or cavern sections according to the preset stability assessment strategy to obtain the global stability assessment results of the surrounding rock of the cavern units or cavern sections. In this assessment process, the global stability state of the surrounding rock of the underground cavern can be quickly, effectively, and accurately judged, and a concrete, practical and effective quantitative assessment solution is realized and provides strong data guidance for engineering practice work involved in the underground cavern.
The above is the introduction of the quantitative assessment method for the global stability of surrounding rocks of underground caverns according to the present application.
