摘要
Abstract
A hydropower station is affected by geological conditions and poor curtain grouting effect,and the leakage of the reservoir is generally large after completion.In order to solve the reservoir leakage problem of the hydropower station,the authors expound the investigation and comprehensive analysis of the reservoir leakage through the long-term observation of the groundwater level,hydrogeological test and tracer test,finds out the main leakage areas and leakage channels,and puts forward the leakage treatment scheme.The results show that the leakage of the reservoir is reduced by 1.3 m3/s after reinforcement grouting,which meets the needs of relevant specifications and safe operation of the power station.The engineering experience is summarized:the leakage treatment of mudstone and sandstone interbedded strata with steep dip fissure development needs to focus on controlling the parameters such as grouting hole spacing and grouting pressure.关键词
