Arch dam monitoring system applied to water conservancy and water power engineering

Abstract

The invention discloses an arch dam monitoring system applied to water conservancy and water power engineering. The arch dam monitoring system comprises a video collection device, a signal transmission device and a computer monitoring center; the video collection device is used for collecting video images of important positions of an arch dam, the video images collected via the video collection device are transmitted to the computer monitoring center via the signal transmission device, the video images are processed via the computer monitoring center, vibration displacement curves of different positions can be obtained, and the arch dam can be monitored via analysis of the vibration displacement curves. The beneficial effects of the arch dam monitoring system are that damage that can be caused to the arch dam can be timely found out, damage positions can be rapidly discovered, and therefore various kinds of engineering measures can be taken for restoration and reinforcement; the system is characterized by simple form, convenience of construction, easy-to-maintain property, low project construction cost, convenience of operation and management and easy-to-change video collection device.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower intelligent monitoring, in particular to an arch dam monitoring system 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 arch dam. In addition...

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

In addition, since the current sensors are generally pre-embedded into the dam body during the construction period of the arch dam, long-term operation will cause the sensor to fail and cannot be replaced, and the effective monitoring of the dam body will be lost. Can not be accurately grasped, causing safety hazards in the operation of the arch dam
