摘　　要：高水头、长距离引水的水电站压力管道采用回填管形式可明显地降低工程造价,加快施工进度;同时,回填管回填土石后,能够恢复原来植被,保护生态环境,且较适于地形坡度小于20°地面布置。南梦3水电站压力管道属国内设计的首例水电站高水头回填管,其设计、施工及运行的成功实践具有较大的推广价值。For high-head and long-distance head conduit of hydroplant, using backfill-conduit form can reduce project cost and accelerate construction progress obviously. Moreover, the earth-rock backfill of head conduit can recover early plant cover, and the layout is fit for terrain where topographical falling gradient is less than 20 degrees. The head conduit of Nam Mang Ⅲ hydmpower station is the first high-head backfill-conduit designed by domestic designing institute, whose successful designing, construction and operating experience is worth generalizing.
