某水库建成运行多年,坝体出现不同程度的渗漏,需要进行大坝渗流安全分析评价.笔者通过对水库大坝坝基扬压力、渗流量监测资料进行分析,结合水库大坝运行表现,对大坝渗流安全进行分析评价.结果表明:坝体内部渗流通道复杂,防渗体系存在薄弱环节,坝体渗流量监测手段落后,监测精度和效率较低;水库大坝渗流性态不安全,建议进一步采取处理措施,及时消除隐患,确保大坝运行安全.
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.
