伪随机流场法在水库渗漏检测中的应用

水库堆石坝渗漏危害坝体安全,如不及时处理,将导致严重后果。以某水库堆石坝右岸渗漏检测为例,介绍了伪随机流场法的工作原理和工作方法,采用该方法查清了右岸坝后及灌浆廊道渗漏的水库渗漏入水点,并结合坝后绕渗孔水位监测、渗漏流量监测等方法综合分析得知,检测的结果与已有的工程地质资料及水工观测资料一致。笔者同时还对渗漏通道、渗漏原因进行推断分析,为该水库渗漏修复整治提供了可靠依据。

The Application of Psuedorandom Flow--field Method to Detecting a Dam Foundation Leakage

Reservoir rock--fill dam leakage will destroy the dam. If it wasn＇t dealt with on time , there would exist serious problems. The paper, taking a reservoir rock--fill dam leakage detecting for an example, introduces the principle and method of the psuedorandom flow--field method. The method is adopted to detect the leakage of reservoir leakage into the water in the right dam and grouting gallery. With the infiltration hole water level and seepage flow amount monitored, the result is in line with the present engineering geological data and hydraulic observation data. In addition, the leakage passage and the reason for leakage are analyzed for providng evidence for the reservoir leakage repairing and renovating.
