摘要
Abstract
The dam site of the lower reservoir of Guigang Pumped Storage Power Station is located above the contact zone between granite and sandstone,and there is water conductivity in this area.There is a low water level trough in the sandstone section of the right abutment,which has a risk of leakage.Based on the topography and hydrogeological conditions,the authors analyze and study the causes of the low groundwater level and the leakage channel of the right abutment,and put forward the design scheme of curtain grouting anti-seepage with double-layer grouting gallery.The results show that the daily leakage after curtain grouting accounts for about 0.03‰ of the total storage capacity,and the anti-seepage effect is remarkable.The research can provide reference for similar engineering design.关键词
