摘　　要：在喀群一级电站压力前池设计中,针对压力前池排冰排沙要求,结合水力学模型试验,通过对压力前池布置不断进行优化,最终确定采用正向排冰、侧向引水布置,排冰闸布置在引水渠末端,压力前池上游,冬季排冰运行时利用上层水排冰,引下层水发电,在进水室前端布置排沙涡管。经过多年运行,运行效果较好。During the design of pressure forebay of Kaqun Cascade I Hydropower Station, in view of the requirements for ice and sediment discharge, combined with hydraulic model test, the forebay layout was constantly optimized.The finally determined scheme is forward ice discharge and lateral water diversion. The ice discharge gate is arranged at the end of diversion channel and upstream of forebay. In the winter, the water of upper layer is used to discharge ice and the water of lower layer is used for power generation. The sediment discharge vortex tube is arranged at the head of water inlet chamber. Multiple years of operation has proved good effects of design.
