摘要
对汉江蜀河水电站工程二期上游围堰断面进行了有限元渗流及边坡抗滑稳定计算,在此基础上对围堰进行了渗流安全评价和稳定性安全评价。计算结果表明:设计采用土工膜作为围堰防渗心墙是合理的,其防渗效果是显著的;围堰断面基本满足规范要求。所获成果为该水电站工程二期上游围堰工程设计提供了依据,对于其它类似工程设计也具有一定的参考价值。
The seepage FEM calculations and slope stream cofferdam of Han River Shuhe hydroelectric stability analysis are conducted for the second upstation engineering. On this basis,the paper evaluates the safety of the seepage and the slippage resistivity of the cofferdam. The results reviews that the geomembrane is used for the cofferdam core,which is reasonable,and the seepage restivity is obvious. The cofferdam satisfies the specification. The computed results provides the basis for reinforcing the second upstream cofferdam of the hydroelectric station engineering. It can be also a useful reference material for analyzing the security of other geomembrane core cofferdam.
