摘　　要：输排冰运行是引水式水电站冬季运行的主要方式之一，顺利有效地输排冰是清除冰害，保证水电站冬季安全运行的首要问题。新疆地区建有大批引水式水电站，由于该地区气候特点，大都采用输排冰运行方式，为此近年进行了大量压力前池输排冰结构布置型式的试验研究工作，通过系列模型试验得出输排冰运行条件，给出了反映输排冰效果的无量纲参数冰水比Ｋ值最大时不同排冰形式的优化布置方案，为引水式水电站输排冰设计提供了参考依据。The operation of ice delivery and sluicing is one of main operation ways of the diversiontype hydropower station in the winter.How to deliver and sluice the ice smoothly and effectively is the key problem to guarantee safe operation of hydropower station in the winter.There are a lot of diversiontype hydropower stations in Xinjiang,Due to the climate features,most of these stations adopt the operation of ice delivery and sluicing.In recent years,a lot of tests and studies on the structural arrangement for ice delivery and sluicing in pressure fore bay have been conducted.The operation conditions of ice delivery and sluicing have been gained by a series of model tests.The optimal layout schemes of different ice sluicing ways have been given. The ratio of ice to water,a nondimensional factor reflecting the effectiveness of ice delivery and sluicing,is maximum. All these provides the reference basis for the design of the ice delivery and sluicing of the diversiontype hydropower station in winter.
