Description

A continuous monitoring device for hydraulic reservoir dam surface deformation

technical field

The invention relates to a continuous monitoring device for surface deformation of a hydraulic reservoir dam body, in particular to a detection environment with hidden safety hazards of the dam and large surface area and relatively high real-time automaticity of detection.

Background technique

As a key hub project of a major water conservancy project, the stability and safety of the dam is directly related to the normal operation of other auxiliary projects of the entire water conservancy project, and directly affects and determines the overall safety and design benefits of the major water conservancy project. Its stability and safety are directly related to the life and property safety of the people in the downstream area, social and economic construction and ecological environment safety.

After concrete dams and masonry dams are built and used as water storage reservoirs, the dam body will inevitably deform under the effects of water pressure, sediment pressure, wave pressure, uplift pressure, and temperature changes. It is a normal phenomenon that the deformation of the dam body and the changes of various loads and influencing factors have corresponding regular changes and are within the allowable range. However, the abnormal deformation of the dam body is often the harbinger of the dam failure accident. According to the continuity of monitoring, it is divided into manual periodic monitoring and online continuous monitoring. The surface displacement monitoring methods of the dam body include two categories: 1) according to the elevation and position of the base point, use theodolite, level, electronic range finder or laser collimator, GPS, intelligent total station, etc. to measure the punctuation points and target points on the dam body surface This method can realize the three-dimensional displacement data measurement of the measuring point; 2) install or bury some displacement monitoring instruments on the surface of the dam body, this method can usually only measure the single item displacement data of the measuring point. The internal displacement monitoring of the dam body is mainly realized by installing buried instruments, usually only a single displacement data (horizontal displacement or vertical displacement) of the measuring point can be monitored. These two types of monitoring methods both use punctuation on the surface of the dam body or install or bury some instruments for monitoring displacement. The initial construction volume of the project is large. Although the instruments are buried for testing and testing, only the measurement points can be measured in the actual testing process. Single-item displacement data is not suitable for the detection environment where the surface area of the dam is large and the real-time detection requirements are high. The data obtained from the detection can explain certain problems, but there is a certain error with the time deformation of the dam surface. It is inconvenient to set monitoring instruments at fixed points, and it is difficult to determine the faulty monitoring point in a short time, which brings a certain threat to the stability of the dam surface monitoring. In order to obtain more comprehensive and accurate data on the deformation of the dam surface, especially For reservoir dams with large safety hazards, it is more necessary to detect the overall deformation of the dam in real time in a wide range and quickly.

At present, related patents related to continuous monitoring of reservoir dam surface deformation include: a method for monitoring the total deformation of an arch dam (201410070397.1), a detection device and method for the reference point of reservoir dam subsidence and horizontal displacement (201410450657.8), distributed Monitoring system (201510749940 .5), reservoir dam subsidence and horizontal displacement monitoring system (201410450695 .3), etc., one of the arch dam full deformation monitoring methods is in the corridor or observation room at different elevations of a certain section of the arch dam Set up monitoring instruments, and calculate the corresponding deformation of the upper dam body at the position of the monitoring point when the vertical line has not been installed through the monitoring results of the inclination monitoring instruments, so as to obtain the actual total deformation of the arch dam. The detection point of this method is fixed, and the representativeness of the detection point is limited. There is a certain error between the actual deformation obtained by calculation and the real deformation; the detection device and detection method of the reference point of the reservoir dam subsidence and horizontal displacement, and the reservoir dam subsidence and horizontal displacement monitoring system They are all detections with fixed monitoring points, and the mobility of the device is poor, requiring long-term debugging; the dam internal view distributed detection system is installed inside the dam body to detect the internal displacement of the dam body, and monitor the surface of the dam body Not involved; therefore, when testing a large-area dam surface, it is necessary to design a comprehensive and rapid real-time detection device to detect the actual condition of the dam surface to the greatest extent.
