摘　　要：溪古水电站溢洪洞为无压竖井旋流洞,针对溢洪洞的上平段坡比、起旋器的尺寸、竖井底部的深度、下平段孔口尺寸等进行了优化,解决了泄水建筑物的流态及消能问题。The spillway tunnel of Xigu Hydropower Project is the pressure free vortex one. Optimizations in terms of the slope ratio of the up- per horizontal section of the spillway tunnel, size of the vortex generator, depth at the shaft bottom, and size of the outlet of the lower horizon- tal section are performed, improving flow pattem and facilitating energy dissipation. Those optimizations are applied in the engineering as well.
