Soil and rock stratum hidden danger information evaluation method and system based on same-hole measurement

Abstract

The embodiment of the invention discloses a soil and rock stratum hidden danger information evaluation system based on same-hole measurement. The soil and rock stratum hidden danger information evaluation system comprises a multi-source information statistical analysis and storage unit, a same-hole monitoring device and a real-time prediction and early warning platform. Soil and rock stratum indexes obtained by the same-hole monitoring device are transmitted to the multi-source information statistical analysis and storage unit to be analyzed and processed, hidden danger information of the soiland rock stratum is evaluated through the real-time prediction and early warning platform, and collapse risk prediction and early warning are achieved. The method comprises the steps that a stratum core sample is drilled, a monitoring hole and an auxiliary detection hole radiating outwards with the monitoring hole as the center are formed, quantitative indexes of the physical property and the mechanical property of the soil body core sample are obtained, and a soil body soft stratum distribution model is constructed in combination with adjacent well geological survey data. The same-hole monitoring of geological, hydrological and deformation multi-source information is realized, the space-time four-dimensional dynamic information of the underground water level, the in-hole osmotic pressure, the deep displacement and the hole wall inclination angle can be acquired in real time for a long time in an unattended operation environment, the hidden danger monitoring cost of a soil layer and astratum is saved, the monitoring accuracy is improved, and the monitoring efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of hidden danger evaluation of soil and rock strata, and specifically relate to a method and system for evaluating hidden danger information of soil and rock strata based on same-hole measurement. Background technique [0002] With the continuous development of underground space, the original stable soil and rock formation environment gradually changed, resulting in the gradual generation of loose, hollow and other unfavorable geological bodies in the underground soil layer. Due to the long-term interference of external factors, these underground hidden patients continue to develop upwards, and finally develop to the ground, and then the ground collapses. Sudden surface subsidence poses a huge threat to people's life and property safety and production and life, and also brings great damage to engineering structures and the natural environment. [0003] At present, the long-term mon...

Problems solved by technology

[0004] For this reason, the embodiment of the present invention provides a method and system for evaluating hidden danger information of soil and rock strata based on the same hole measurement, so as to solve the problem that in the prior art, the long-term monitoring of the physical and mechanical properties of the soil layer often adopts "monitoring by holes". method, its automatic monitoring level is low, the efficiency is low, and the cost is high; in addition, the environment of soil and rock strata is becoming more and more complex, and the traditional "monitoring and early warning technology" can no longer meet the current requirements of soil and rock stratum collapse tendency evaluation and early warning.
