摘　　要：结合我国一些水电站工程，对导流洞改建为旋涡式竖井溢洪道进行了综合研究。首次采用了压力短进水口出流为急流的引水道分别同涡井和涡室两种旋涡结构的连接型式，通过水工模型试验优选涡井（室）体型，并系统地研究其设计方法和水力学特性，为今后旋涡式竖并溢洪道设计提供了依据。In combination with some hydro projects's practice, an integrated study was conducted to change diversion tunnels into vortex type vertical shaft spillways. It is the first time to use short pressure headrace tunnel and speed out flow combined with a vortex structure of volute well or volute chamber. The well (chamber) was optimally designed through hydraulic modeling. Its hydraulic characteristics and its design were systematically observed to provide the design of vortex vertical shaft spillways with a scientific basis.
