Comprehensive monitoring system and monitoring method for rock mass degradation of valley area bank slope hydro-fluctuation belt

Abstract

The invention provides a comprehensive monitoring system and monitoring method for rock mass degradation of a valley area bank slope hydro-fluctuation belt. The monitoring system comprises a data collection module which is connected with a plurality of fixed clinometers, a plurality of displacement meters, a plurality of surface crack meters, a plurality of soil pressure cells, a plurality of automatic thermometers, a water level gauge and a rain gauge, a plurality of integrated multi-antenna GNSS receivers, a GPRS data transmission device, a Web, a database server, an early warning module which is used for sending out early warning information when judging that the monitoring data exceed an early warning value, a cloud server which is used for receiving the data automatically uploaded by the Web and the data server, and also can be used for receiving the test data manually uploaded, and a user terminal which obtains early warning information through an early warning module, and obtains and cancels the monitoring data of each physical quantity of the hydro-fluctuation belt through a cloud server. The method has the beneficial effects that deformation and stress changes caused by bank slope hydro-fluctuation belt rock mass degradation with different landform characteristics and rock mass quality can be effectively monitored, and comprehensive degradation parameters of the bank slope hydro-fluctuation belt rock mass can be fully obtained.

Description

technical field [0001] The invention relates to the technical field of geological disaster prevention and early warning, in particular to a comprehensive monitoring system and monitoring method for rock mass degradation in a bank slope drawdown zone in a canyon area. Background technique [0002] With the increasing number of large-scale water-storage hydropower stations, the water level in the reservoir area is fluctuating when the hydropower stations are storing water, and the surface water and groundwater are extremely active near the bank slope of the reservoir area. Different degrees of macro-deterioration will occur on slopes. Slopes with water-level fluctuations affected by water-level fluctuations and with strong rock mass degradation effects are called slope-fluctuation zones. Due to water-rock action, hydraulic erosion, stress and environmental periodic action, bank-fluctuating zones with different structural and lithological conditions show significant differences...
