| 摘 要： | 西安市黑河引水一期工程－石砭峪水库泄洪洞弯段布置为大底坡急流弯道，为调整其体形和水流流态，进行了水工模型。根据隧洞已开挖成洞的现状，又要较好地控制道段水流态的要求，试验中道对不同弯道体形进行了多次比较和修改，其中复合圆弧曲线弯道体形较好地控制了急流大弯道大流流态。

| Abstract: | The Shibianyu spillway tunnel contains a horizontal rectangular bend with free surface flow and a slope i=0.1 of the several designs analysed according to the existing excavation status and laboratory test, the compound bend with three centered arc was finally chosen and can produce fewer disturbances of shock to minimize the water surface fluctuation. The flow control in this type of bend were discussed and the approach of hydraulic design was also suggested in this paper. |
