摘　　要：大石门水利枢纽工程左岸205 m巨厚砂砾石层古河槽,水库蓄水后存在渗漏问题。通过三维渗流计算方法对左岸古河槽进行渗流稳定计算分析,模拟选取的防渗帷幕布置,分析防渗措施的长度及渗流参数对渗漏量的影响,为防渗措施方案的选择提供了指导意义。The ancient river channel in 205 m hugely thick sandy gravel on left bank of Dashimen project seeps after the reservoir impoundment. Through 3 D seepage calculation method,seepage stability of the river channel is calculated and analyzed. The proposed impervious curtain arrangement is simulated. Impacts on seepage volume from the length and seepage parameter of the impervious facility are analyzed. This guides selection of scheme for the impervious facility.
