Description

TECHNICAL FIELD

The present disclosure relates to the technical field of geological disaster monitoring and prevention, and particularly relates to an arrangement apparatus for multiple integrated sensors in a deep position of a sliding mass and an arrangement method.

BACKGROUND

As a common geological disaster, landslide most frequently and widely occurs in nature, seriously threatening our living environments, natural resources, water conservancy projects, etc. It is reported that since the initial impoundment of the Three Gorges Reservoir in 2003, a large number of ancient landslides re-slide owing to periodic water level fluctuation of the Reservoir and rainfall, which has great potential danger. The deformation of landslide is evolved dynamically and spatiotemporally, basic landslide features are closely correlated and matched with evolution stages and evolution models, and the evolution process is usually accompanied with multi-field coupling features.

Single-hole multi-sensor integrated arrangement has become an important aspect in continuous development of the technology for monitoring landslide multi-field information in recent years. In view of the defects of low efficiency, high cost, poor correlation, etc. in an existing multi-instrument independent distribution type integrated monitoring method, a concept of “multi-measurement in one hole” has been gradually proposed in recent years and considered promising by the engineering geologists. Although the “multi-measurement in one hole” is generally considered promising and has developed substantially, it still has technical defects. For example, a monitoring instrument is installed in a hole in an existing monitoring method, which is suitable for deep inclination measurement and underground water level measurement, but cannot accurately measure parameters of pore water pressure and water content etc. in situ. Moreover, the method has poor environmental adaptability, and when the landslide deformation is increased, the instrument in the hole is prone to damage and malfunction, so a multi-information parameter monitoring technology of “multi-measurement in one hole” is not workable under the in-situ condition. Meanwhile, under the condition that soil on the side wall of the borehole is compact and part of sliding mass is made of gravel soil or more compact materials, arrangement of the multi-parameter sensor in the borehole is often challenging. Therefore, it is important to develop the multi-information parameter monitoring technology capable of achieving “multi-measurement in one hole” in situ and a corresponding arrangement device for an underground multi-parameter monitoring sensor.
