Landslide real-time monitoring system and method

Abstract

The invention belongs to the technical field of landslide monitoring, and particularly relates to a landslide real-time monitoring system and method. The system comprises a stress measurement system and a data collection and transmission system. The stress measurement system comprises an anti-slide pile and a deformation sensor fixed on the anti-slide pile, and the anti-slide pile is fixed in an area, which does not slide, of the lower part of a landslide body; and the data collection and transmission system is connected with a deformation sensor and is used for acquiring and transmitting dataoutput by the deformation sensor. The deformation sensor is fixed on the anti-slide pile; the anti-slide pile is fixed in a relatively stable area which does not slide, the movement along with the landslide body is avoided, the landslide real-time monitoring system and method can stably monitor the state and stress change of a landslide body, the deformation sensor is connected with the data collection and transmission system, real-time transmission and observation of data can be achieved, the real-time monitoring of the landslide body and the safety of data acquisition personnel are ensured,and compared with a traditional optical fiber monitoring system, the monitoring cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of landslide monitoring, in particular to a landslide real-time monitoring system and method. Background technique [0002] Landslide monitoring is to determine the state of the landslide by detecting the relevant physical parameters of the landslide, such as the depth of the sliding surface, the direction of the sliding surface, the amount of movement of the landslide, and the speed of movement. According to the type of monitoring, landslide monitoring can be divided into deformation monitoring, physical and chemical field monitoring, meteorological and groundwater monitoring, etc. The contents of physical and chemical field monitoring include stress monitoring, geoacoustic monitoring and temperature monitoring. The monitoring technologies used in stress monitoring include steel bar gauge, anchor cable gauge, earth pressure gauge, laser measuring gauge and distributed optical fiber stress sensor. [0003] ...

AI Technical Summary

Problems solved by technology

The advantage of this method is that the data is transmitted, and the data can be read in real time by reading the signal transmitted by the optical fiber; the disadvantage is that the embedding of the optical fiber is complicated, and the cost is dozens of times that of the traditional stress measurement method.
