复合土工膜因其诸多优点在我国得到了一定应用，但对其实际防渗效果的综合评价尚缺乏理论依据。以采用该方法进行防渗加固的东海县狼墩水库为例，利用有限元法计算分析加固前后坝体渗流特性。分析结果表明，以复合土工膜为主要防渗措施建立的防渗体系效果良好，可明显改善坝体和坝基的渗流性态，加固后大坝各料区渗透坡降和渗透流量均明显减小，能满足规范要求，且该方法施工质量可靠。

Composite geo-membrane has been certain used in China because of its advantages. However,evaluation of its actual anti-seepage effect still needs more theoretical basis. Based on Langdun reservoir dam,adopted this way for reinforcement,finite element method has been used to computational analysis the characteristic of the dam structure before and after the reinforcement. The results show that the effect of the anti-seepage system with Composite geo-membrane is good and the seepage condition of the dam body and foundation is demonstrably improved. After the reinforcement,the seepage slope of each partition and seepage discharge both significantly reduced. And the construction quality of this reinforcement approach is reliable.
