山西张峰水利工程大坝反滤层渗透稳定性分析

Analysis on Inverted Filter's Seepage Stability of Zhangfeng Water Conservancy Engineering in Shanxi Province

山西张峰水利工程是山西省重点工程,其大坝为粘土斜心墙堆石坝,通过颗粒分析、接触冲刷、接触流失和裂缝冲刷试验,分析了大坝反滤层的渗透稳定性,证明大坝反滤层设计的合理性,并探讨了土石心墙坝反滤层渗透稳定性的几个问题,供类似工程参考。

Zhangfeng water conservancy engineering in Shanxi Province is a major project of Shanxi Province. Its main dam is a sloping core earth-rockfill dam. Through such the tests as grading analysis, contact efflux, contact scour and crack scour, the filters seepage stability of the main dam is analyzed, the rationality of design for the filter is confirmed, and some problems about the seepage stability of the sloping core earth-rockfill dam are discussed. The outcome can be referencs for other similar engineerings.
