摘要
湖南镇大坝１２＃坝段挡水运行不久，曾发生帷幕后部渗漏量骤增、扬压力超限异常现象，经灌浆处理帷幕后部渗流恢复正常运行状态。本文依据长系列渗流观测资料。
Soon after the impoundment operation of the monolith No.12 of Hunanzhen dam, the abnormal phenomena occured——the leakage amount at the rear curtain increased heavily and the uplift pressure exceeded the limit value. Through grouting treatment, the seepage at the rear curtain recovered to the normal operation condition. This paper synthetically analyses the curtain stability of the monolith No.12.
