Study On Stability And Monitoring Of Dam Body Of Jinanqiao Hydropower Station

Hydropower station dam is a huge investment bringing great benefits and risks of the project. Its important an role in flood control, water storage, power generation, irrigation, urban water supply, aquaculture, tourism and so on many aspects. Most of the dams have had a remarkable social and economic benefits in the course of use, but some of them caused accidents. As is well known, once happened the dam accident will be very serious. Dam monitoring is an important way to protect the dam body stability. In fact, the early find of the dam deformation and other problems can reduce the probability of damage.The main work of this thesis is based on the numerical simulation combined with vacuum collimation monitoring data, which demonstrated and analyzed the stability of Jin’anqiao Hydropower dam Station. The main work and results are as follows:(1) introduces the Jinanqiao Hydropower Station Engineering Geological and hydrogeological conditions. The factors that affect the stability of the dam are analyzed in theory.(2) based on the principle of limit equilibrium this paper used Lizheng geotechnical analysis software of dam parameters configuration and the stability of the dam are calculated, the result of the theoretical level of stability is obtained. For on-site monitoring of some requirements and methods such as distributed optical fiber sensing technology, triangulation and direction method to measure phase orange synthetic method for the synthesis of release, resection, Oriented and direction of change in conjunction synthesis method, vacuum laser collimation monitoring method are introduced. The method of selecting the vacuum laser alignment monitoring.(3) the organization of construction, airborne software were introduced and actual detection in bedrock deformation instrument, measuring oblique instrument embedment, composed of 12 points of plane monitoring network is established. In Jin’anqiao Hydropower Station external deformation monitoring control network implementation, the use of advanced instruments, process specification, statistics and record the monitoring results of the instrument and the data take scientific and rigorous analysis, obtained the excellent quality of the results.
