A method and system for evaluating hidden danger information of soil and rock strata based on same-hole measurement

Abstract

The embodiment of the present invention discloses a soil and rock formation hidden danger information evaluation system based on the same hole measurement, which includes a multi-source information statistical analysis storage unit, the same hole monitoring device and a real-time prediction and early warning platform; The rock formation indicators are transmitted to the multi-source information statistical analysis storage unit for analysis and processing, and the real-time prediction and early warning platform is used to evaluate the hidden danger information of the soil and rock formations and realize the collapse risk prediction and early warning. The method is as follows: drill core samples of the stratum and form monitoring holes and auxiliary detection holes centered on the monitoring holes to radiate outwards, obtain the physical and mechanical quantitative indicators of the soil core samples, and combine the geological survey data of adjacent wells to construct soil Weak formation distribution model. The present invention realizes the same hole monitoring of geology, hydrology, and deformation multi-source information, and can obtain the time-space four-dimensional dynamic information of groundwater level, seepage pressure in the hole, deep displacement, and hole wall inclination in real time for a long time in an unattended environment, saving soil Reduce the cost of hidden danger monitoring in layers, improve monitoring accuracy, and improve monitoring efficiency.

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.
