seepage of dam foundation

Study on Seepage of the Gate Dam on the Foundation of Deep and Overburden Layer With 3-D FEM

深厚覆盖层闸坝坝基的三维有限元渗流分析

The over-burden layer of dam foundation is up to 147.95 m thick and is strong pervious easy collapse and easy slurry-leakage and hard rock blocks so that it is difficult to treat the seepage of dam foundation.

坝基覆盖层厚达147.95m，透水性强，易坍塌和漏浆，块石坚硬，坝基防渗处理难度罕见。

The seepage stability is solved by width core and thick filter. The paper introduces the design of dam profile, dam material subzone, measures of dam slope earthquake resistance stability, design of foundation treatment and practical operation.

文章介绍了大坝的剖面设计、坝体材料分区、坝坡抗震稳定处理措施、基础处理设计以及实际运行等情况。

In-situ test of fractured rock mass with high pressure seepage in dam foundation

坝基破碎岩体高压渗透变形原位试验

The seepage in dam foundation in Baishan reservoir has been analyzed in detail from many aspects, including underground water outcropping, icing on the surface of reservoir, geological condition of dam foundation and the geophysical detection results, sediment and so on.

从白山水库坝下游地下水出露现象、水库水面结冰现象、坝基地质情况及物探检测结果、沉积条件等多个方面对水库坝基渗漏情况进行了详细分析。

The role of drainage for dam foundation is to shorten the seepage path and increase the seepage gradient, thus dissipating rapidly the uplift pressure during drainage.

坝基排水的作用是缩短渗径、增大渗透坡降，而使扬压力迅速消散于排水中；
