摘　　要：泸定水电站坝基防渗墙顶部设置灌浆观测廊道,河床和右岸灌浆廊道均置于覆盖层上,在左岸岸边与岩基搭接。通过大坝三维应力应变分析,对灌浆廊道结构缝分缝位置进行了分析研究。同时,详细介绍了廊道结构缝止水设计及抗渗、抗裂措施。A grouting gallery is arranged on the top of darn foundation cutoff wall in Luding Hydropower Station. The right and river-bed sections of grouting gallery are arranged on the deep overburden and the left section is lapped on the let~ rock foundation. By three dimensional dam stress and strain analysis, the structural joint positions of the grouting gallery are studied. The water stop design for the structural joints and the measures on crack resistance and seepage control are also introduced in detail.
