摘　　要：通口水电站是以发电为主,采用混合开发方式的综合性水利枢纽工程,坝高73.5 m。本文结合水工模型试验成果,论述了通口电站冲沙底孔的过流能力和流量系数,研究了冲沙底孔体型布置对廊道压力、消能防冲及电站尾水等的影响,提出了改善冲沙底孔廊道压力和改善消能防冲条件的工程措施,该研究成果已被设计采用。Tongkou power station is an all -round hydro project, where the mixed exploitation mode is adopted with mainly for power generation. Integrated with the model test result, the duct discharge capacity and flow coefficient in various discharge hole are discussed, the influence of duct shape on inlet pressure i energy dissipation and tail water is analyzed, the improvement measures on conveyer way pressure and energy dissipation are put forward too. The achievements of this study have been adopted by the designers.
