A remote real-time early warning method for landslides on granite residual slopes of mountain expressways

Abstract

The invention relates to a mountain highway granite residual colluvial soil landslide remote real-time early-warning method. The method includes the following steps that: a potentially destructed slope is selected, and the positions of potential main slide lines or main slide surfaces of the slop are obtained; monitoring points are arranged at the positions of the main slide lines or main slide surfaces, and sensors are embedded at the positions; the sensors acquire slope deformation and displacement data in real time and transmit the data to a data acquisition station through an optical fiber cable, and the data acquisition station automatically transmits received monitoring data to a remote client end in real time; the remote client end performs formatting processing on the data; processed data are calculated through adopting a fitting curve slope prediction method and a catastrophe theory prediction method, so that critical failure time and unstability time of the potentially destructed slope can be obtained; and landslide time change trends under different states can be obtained according to the critical failure time and unstability time, and early-stage early warning and forecast about the dangerous case of the slope can be performed according to the landslide time change trends. Compared with the prior art, the mountain highway granite residual colluvial soil landslide remote real-time early-warning method of the invention has the advantages of high early-warning and forecast precision, high reliability and the like.

Description

technical field [0001] The invention relates to a real-time early-warning and forecasting method for mountain landslides, in particular to a remote real-time early-warning method for soil-accumulated landslides on granite residual slopes of mountain highways. Background technique [0002] In recent years, geological disasters such as earthquakes, landslides, and debris flows have occurred frequently at home and abroad, especially in my country. Due to the excessive development of resources, the natural environment has deteriorated seriously, and various geological disasters have caused great harm to people's lives and property safety. . In addition, with the continuous construction of infrastructure such as large-scale hydropower stations, reservoirs, highways, and railway projects, destructive disasters such as landslides, embankment bursts, and collapses have also seriously affected the safety and life of these infrastructures. According to incomplete statistics, tens of t...
