针对清江水布垭水利枢纽河岸式溢洪道具有泄量大、水头高、下游消能区环境地质差等特点，通过1∶100整体模型对一级挑流消能防冲布置及消能形式进行了3个方案试验研究，结果表明：方案三的引渠流速、流态、水面比降、泄流能力及下游冲刷等的水力学指标基本上能满足设计要求，并指出还有待研究的问题。

Abstract The features of the Shuibuya Project's bank spillway are high head,large discharge and bad geological conditions in the downstream dissipation area.Hydraulic model tests on three dissipation schemes were conducted.The test results show that the values of hydraulic parameters of the third schemes,such as velocities,flow patterns and water surface slopes in the approach channel,the condition of the discharge capacity and downstream erosion,can basically satisfy the requirement of design,so it is recommended.Some problems still needed to be studied are pointed out . 
