Seepage Behavior Analysis and Evaluation of Concrete Gravity Dam in a Reservoir
A reservoir has been built and operated for many years,and the dam body has different degrees of leakage.It is necessary to analyze and evaluate the seepage safety of the dam.Based on the analysis of the monitoring data of the uplift pressure and seepage flow of the dam foundation of the reservoir dam,combined with the operation performance of the reservoir dam,the seepage safety of the dam is analyzed and evaluated.The results show that the seepage channel inside the dam is complex,the anti-seepage system has weak links,the monitoring methods of dam seepage flow are backward,and the monitoring accuracy and efficiency are low;The seepage behavior of reservoir dam is not safe.It is suggested to take further measures to eliminate hidden dangers in time to ensure the safety of dam operation.
