摘　　要：旋流式竖井,涡室水边线问题一直是研究的重点问题。目前,旋流式竖井涡室水边线的计算并没有明确的理论计算方法,主要依赖水工模型试验测量得到的试验数据。通过Ippen冲击波理论和刘韩生缓冲击波简化式分别计算了涡室水边线,对比栗西沟旋流式竖井试验数据,得知后者计算精度更高,计算过程更加简单,可满足工程的需要。Cycloneshaft is an excellent sluiceway and water edge has been a significant issue to study. However,at present,there is no definite calculating method to study the water edge of cyclone shaft and the primary method of it is experimental data in experimental study. This paper studied the issue of water edge by using Ippen shock wave theory and Liu Hansheng simple shock wave theory and contrasted the experimental data of Lixigou cyclone shaft. The precision of the latter was higher and counting process of the latter was easier. So we could resolve the issue of calculating water edge of volute chamber and it could meet the demand of engineering.
