摘要： 结合雅砻江两河口水电站后期3^#导流洞和大渡河猴子岩1^#导流洞的改建，在研究旋流阻塞和旋流扩散复合消能泄洪洞的水力特性基础上，对该类型复合式旋流内消能泄洪洞的设计原理与方法进行研究探讨，和开敞式进口、起旋器、阻塞与旋流渐变扩散段的体型进行了设计与计算，为1 000m³/s以上泄流量、150m作用水头量级的导流洞改建为旋流内消能泄洪洞工程水力设计提供参考。

Abstract: On the basic research of hydraulic characteristics of the compound expression spillway tunnel of inner energy dissipation with vortex-flow block and vortex-flow divergent, when the diversion tunnels are reconstructed from Lianghekou Hydroelectric Station and Houziyan Hydroelectric Station, the principle and method of hydraulic design are researched,and the type of the open intake,vortexflow generator, block and vortex-flow gradually expanded section are designed and calculated. The result offers a reference about hydraulic design in which the diversion tunnel will be reconstructed as a vortex-flow spillway tunnel with discharge more than 1 000m³/sand available pressure head 150 m.
