摘　　要：通过模型试验论证及以往工程应用实例,对库什塔依水电站表孔溢洪道阶梯消能初步设计方案进行优化,增设掺气槽,扩大首级台阶的宽度,使泄洪水流能量在陡槽台阶上大量削减,从而消力池长度由100m缩短至50m,节约工程投资。The preliminary design of the crest outlet spillway energy dissipation in steps for the kushitayi hydropower station is optimized according to the verification by the model test and by the living examples applied in existing hydropower projects.Provision of additional aeration grooves and increase of the width of the first step significantly reduce energy of discharging current on the chute steps,thus greatly shortening the length of the plunge pool from 100m to 50m,saving the cost of the project.
