leakage of dam foundation

A combined measure of paving compound film on the upstream surface of dam and setting up vertical anti-seepage in dam foundation is adopted to treat leakage.

因此一般采用上游坝面铺设复合土工膜和坝基垂直防渗措施进行防渗漏处理。

The rock foundation of the dam of the Dahua Hydro-project was relatively poor, however, both the uplift and water leakage under the dam are fairly low after a comprehensive foundation treatment.

大化水电站大坝基础岩石虽较差，但基础处理采取综合处理措施后，坝基扬压力及渗漏水量均较小。

The paper studies the control function of contact leakage in the connected section between cut-off wall and core of the dam foundation of the Xiaolangdi Reservoir through indoor tests.

通过室内试验研究了小浪底水库坝基防渗墙与心墙连接段的接触渗流控制性能。
