Problems solved by technology

[0003] In related technologies, the health monitoring of the earth-rock dam body is generally carried out through monitoring sensors, but most of the sensors cannot predict the remaining life of the earth-rock dam body based on the monitored data
This defect causes earth-rock dam maintenance personnel to judge the data fed back by sensors based on their own relevant experience, which reduces the timeliness of earth-rock dam monitoring and greatly increases the workload of earth-rock dam maintenance personnel

Abstract

The invention discloses a real-time earth-rock dam body monitoring system with a waste slag field arranged behind a dam. The system comprises a monitoring module, a data processing module, a safety state evaluation module, an early warning and alarm module and a simulation display module, wherein the monitoring module comprises a wireless sensor network, a strain sensor assembly and displacement sensors, the data processing module comprises a collection central station, a signal conditioner and a signal transmission device, the safety state evaluation module comprises a microprocessor, the early warning and alarm module comprises an analysis processor and an alarm device, and the simulation display module comprises a three-dimensional GIS simulation platform. By means of the real-time earth-rock dam body monitoring system, health of an earth-rock dam body can be monitored in real time, the residual life of the earth-rock dam body can be predicted according to monitoring data, and the unprecedented height is reached on the aspect of complete coverage and all-weather monitoring.

Description

technical field [0001] The invention relates to the field of earth-rock dam body monitoring, in particular to an earth-rock dam body real-time monitoring system with a spoil ground behind the dam. Background technique [0002] In hydropower and water conservancy projects, especially in pumped storage power stations, in order to save project land, the layout type of spoil ground is often adopted behind the earth-rock dam. In order to ensure the smooth discharge of water seepage from the dam body and the mountains on both sides, a certain thickness of permeable rockfill material is generally paved at the bottom of the spoil ground, and pressure measurement is buried at the downstream dam foot. [0003] In related technologies, monitoring sensors are generally used to monitor the health of the earth-rock dam body. However, most of the sensors cannot predict the remaining life of the earth-rock dam body based on the monitored data. This defect causes earth-rock dam maintenance ...
