Description

technical field [0001] The invention relates to the technical field of monitoring and prevention of geological disasters, in particular to a high and steep slope stability monitoring system and monitoring method based on microseismic technology. Background technique [0002] The monitoring of rocky slopes has always been a weak link in the process of landslide monitoring and early warning. Existing conventional monitoring methods such as surface displacement, deep displacement, pore water pressure and rainfall monitoring methods are ineffective in response to rocky slope deformation monitoring and early warning and forecasting. There are deficiencies in the process. [0003] Chinese patent CN107015269 A discloses "A Real-time Monitoring System and Monitoring Method for Microseismic Fracturing Based on Wireless Network". The system is mainly composed of a server, a wireless microseismic data collection station, an on-site hand-held inspection terminal and a wireless AP. The s...
