Dangerous rock mass group instability early warning and monitoring system

Abstract

The invention relates to a dangerous rock mass group instability early warning and monitoring system. The system comprises a monitoring sensing module used for collecting dangerous rock mass and meteorological data and sending the data to a data processing module; the data processing module is used for storing, analyzing and processing the dangerous rock mass and meteorological data and transmitting a result to the early warning monitoring module; the early warning monitoring module is used for carrying out disaster grade evaluation and disaster early warning release based on a result obtained by the data processing module; and the monitoring sensing module, the data processing module and the early warning monitoring module are connected in sequence. According to the invention, cross-correlation analysis is carried out on signals acquired by different sensors and attitude information through the data processing module to judge the state of the dangerous rock mass, so that the problems of high cost and untimely early warning of an existing dangerous rock mass early warning method are solved.

Description

technical field [0001] The invention relates to the technical field of early warning and monitoring of dangerous rocks, in particular to a system for early warning and monitoring of instability of dangerous rock masses. Background technique [0002] Dangerous rock is a rock block or block group that is located on a steep hillside or cliff and is cut by multiple rock mass structural planes and has poor stability. form. Dangerous rock mass is a potential collapse body, which can easily cause the collapse of a single rock mass or even the group collapse of multiple dangerous rock masses. The collapse of dangerous rock mass is an important type of geological disasters. It is a natural dynamic geological phenomenon, and it is also a process of engineering geological disasters caused by human activities under the conditions of natural slopes. From the perspective of geological disasters, although the destructiveness of dangerous rock collapse is less than that of an earthquake, ...

Problems solved by technology

From the perspective of geological disasters, although dangerous rock collapses are less destructive than earthquakes, their occurrence frequency and impact range exceed those of earthquakes. This is a serious global mountain disaster problem with strong suddenness, The characteristics of wide distribution, strong disaster-causing ability and certain concealment seriously threaten the normal production and life of traffic arteries and mountain residents; in my country, a large number of casualties and major economic losses are caused by rock collapse every year

[0003] At present, the traditional rock mass monitoring technology generally has some deficiencies. The traditional rock mass collapse monitoring technology mostly performs single monitoring on some areas of the rock mass, and cannot monitor the entire rock mass area in real time. There are large monitoring limitations, resulting in The monitoring data is inaccurate, leading to false warnings. At the same time, the traditional monitoring method is that people use a ruler to directly measure the width change of obvious cracks after the rock mass collapses. This measurement accuracy is poor and there is a certain risk. Due to its highly explosive characteristics, it is impossible to realize the early warning effect before rock mass collapse and damage, thus affecting road traffic safety accidents and threatening the lives and property safety of surrounding residents. Therefore, an early warning and monitoring system for the instability of dangerous rock mass groups is urgently needed
