Method for monitoring and early warning of landslide thrust based on stability coefficient

Abstract

The invention relates to the technical field of geological hazard model test, in particular to a method for monitoring and early warning of landslide thrust based on a stability coefficient. The method comprises the following steps of step one, parameter determination; step two, thrust monitoring; and step three, calculation of the stability coefficient and early warning. Compared with traditionaldetection methods, the method provided by the invention establishes a corresponding relationship between the monitoring data and slope stability by monitoring the landslide thrust to visually and quantitatively display the safety level of the slope, thereby improving applicability and reliability of the monitoring of early warning and forecast of slopes of different types and different states.

Description

technical field [0001] The invention relates to the technical field of geological disaster model tests, in particular to a method for monitoring and early warning of landslide thrust based on a stability coefficient. Background technique [0002] my country has a vast territory and complex geological conditions. Mountains and hills are widely distributed, and landslides are widely distributed. According to the force characteristics of landslides, they can be divided into traction landslides, push-type landslides and mixed-type landslides. Long-term loading leads to the overall destruction of the landslide. In order to effectively protect the safety of people's lives and properties, it is very necessary to monitor the state of landslides in time and give early warning in time. [0003] The current landslide monitoring is mainly based on displacement monitoring, which indirectly reflects the safety of the slope through the accumulated displacement or deformation rate. Early wa...

Problems solved by technology

[0003] The current landslide monitoring is mainly based on displacement monitoring, which indirectly reflects the safety of the slope through the accumulated displacement or deformation rate. Early warning and forecasting only rely on the deformation curve, which is purely an analysis of monitoring data, without considering the rock and soil characteristics of the slope Therefore, its reflection on the safety degree of landslides can only be indirect and qualitative. At the same time, due to the different geotechnical structures, shapes, and influencing factors of landslides, different slopes or even different parts of the same slope will be affected. There are also great differences in the amount of deformation and deformation rate near failure, which reduces the accuracy of displacement-based landslide prediction
