云峰电站坝基F_(15)断层稳定分析

Analysis of dam foundation F_(15) fault stability in Yunfeng hydro power station

云峰水电站在坝基开挖时发现右岸 50～ 51号坝段坝基出露有 F15缓倾角断层，至今没有进行过处理。本文对坝基 F15断层的稳定性进行了分析，认为 51号坝段抗滑稳定不满足要求，故对此提出 5点改进建议。

A mild obliquity fault F15 in 50～51 dam section foundation was discovered during dam foundation excavation in Yunfeng hydro power station. It is not disposed up to now. The paper analyses the stability of the faultage, and thinks that the stability of 51 dam section against sliding do not satisfy demand. The paper puts forward some propositions.
