Problems solved by technology

The above-mentioned monitoring is basically static or quasi-static monitoring. For the stability of the dam abutment and the overall displacement of the dam body, the static method is still applicable. It is difficult to grasp the instantaneous change of the working state of the arch dam and the evolution process over time, and the arch dam's instantaneous arching failure and the arching failure caused by the cumulative effect of cracks will threaten the safe operation of the arch dam

Abstract

The invention discloses an arch dam intelligent monitoring system for water conservancy and hydropower projects, comprising a data acquisition device, a storage device and a computer monitoring center; the data acquisition device is used to collect vibration data at important positions of an arch dam; the data acquisition device The collected vibration data is transmitted to the computer monitoring center and storage device, and the storage device is configured to store the vibration data; the computer monitoring center processes the vibration data to obtain vibration displacement curves at different positions, The monitoring of the arch dam is realized by analyzing the vibration displacement curve.

Description

technical field [0001] The invention relates to the field of intelligent monitoring of water conservancy and hydropower, in particular to an intelligent monitoring system for arch dams used in water conservancy and hydropower projects. Background technique [0002] In related technologies, the monitoring of arch dams mainly includes deformation monitoring, seepage and seepage pressure monitoring, stress and strain monitoring, gap opening and closing degree monitoring, and temperature monitoring. The above-mentioned monitoring is basically static or quasi-static monitoring. For the stability of the dam abutment and the overall displacement of the dam body, the static method is still applicable. It is difficult to grasp the instantaneous change of the working state of the arch dam and the evolution process with time, and the instantaneous arching failure of the arch dam and the arching failure caused by the cumulative effect of cracks will threaten the safe operation of the ar...
