Description

TECHNICAL FIELD

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

BACKGROUND

As a highly dangerous natural disaster, the landslide disaster has a high occurrence frequency, a wide damage range and serious harm, causing a large number of casualties and huge economic losses every year. An important measure for dealing with the landslide disaster is to develop the landslide monitoring apparatus, so as to achieve the landslide prediction and early warning, and then to reduce the loss caused by landslide to the minimum.

Landslide monitoring substantially relies on capture of geological parameter information, including surface deformation, surface runoff, seepage, ground cracks, etc., of the surface of the sliding mass for a long time. Except for deep deformation and seepage, monitoring of the other geological parameter information at the deep position of the sliding mass is limited due to lack of monitoring instruments, and coupling between monitoring data is low. The deformation destruction of landslide is evolved dynamically and spatiotemporally, with the evolution stages closely correlated with the evolution models, and multi-field coupling feature is found. Since the “multi-measurement in one hole” technology is introduced, it has drawn increasing attention from engineering geologists in recent years. Integrated sensors are arranged in a borehole of the sliding mass under an in-situ condition, so as to accurately measure parameters, for example, pore water pressure and moisture content under the in-situ condition, and effectively solve the problems of low efficiency, high cost, poor correlation, etc. of an existing multi-instrument independent distributed type integrated monitoring method. Therefore, based on the idea of “multi-measurement in one hole”, an arrangement device is developed for an underground multi-parameter monitoring sensor in an in-situ environment, which has great significance for monitoring underground multi-information parameters.
