| 摘 要： | 断层及层间挤压错动带采用高压水冲洗置换灌浆的方式进行处理，能够冲洗出一部分软弱介质，冲洗后的空腔再采用水泥浆液进行置换固结灌浆，相当于在断层上施加了水泥柱桩，提高了断层基础的承载力。本文介绍锦屏一级水电站大坝左岸f2断层高压冲洗水泥置换灌浆加固施工技术的成功运用。

| Abstract: | Some loosened medium will be flushed out when handling the fault and interlayer shear zone with high pressure water. Then the cavum will be filled with cement, which is equivalent to adding cement column to fault, improving bearing capacity of fault. Cement grouting technology of F2 fault of Jinp~ng I hydropower station dam foundation is successful. |
