| 摘 要： | 石门拱坝已有２０余年渗流的观测实际资料，８＃～１２＃坝段基础未设灌浆帷幕，出现了一些特殊渗流现象，形成了一个渗流通道，和１＃～７＃坝段坝基渗水显然不一样，扬压力增大，与原设计想法迥然不同。

| Abstract: | Shimen dam is a concrete thin arch dam.Its left part of foundation is calcium schist, the right part is quartz schist. The monitoring material gained in long period of more than 20 years reveals that an unusual seepage phenomenon occurred in the foundation of blocks No.8 to No.12,which had not been grouted to form a curtain, and an unexpected seepage channel happened.The main differences of seepage characteristics between the left and right areas are discussed as well. |
