| 摘 要： | 水工建筑物的进、出口设计要涉及到边墙的设计，随着坝高不断加高，水流流速越来越大，《水工建筑物》的经验公式已不能满足人们的要求。从水流冲击波的生成机理出发，研究了侧边墙的水流特性，从理论上分析了泄槽水流特性与侧边水流特性关系，从而研究出更适合水流流态的边墙偏转角度，并给出了不同边墙偏转角的水力计算公式。

| Abstract: | The intake and exit designs of hydraulic structures generally involve the abutment wall designs.Nowadays,more and more high dams are being built,then the hydraulics problems on high velocity are raised.The relative empiric formulas can't satisfy the requirements of design.From the mechanism of shock waves,the paper presents the characteristics of water flow and flow-pattern in each side of abutment wall,and provides the calculation regions of wall arrangement and corresponding calculation formulas. |

| Keywords: | shock wave abutment wall positive wave negative waves diffuse angle |
