摘　　要：溢洪道泄槽弯道泄流时,弯道段内易产生横向冲击波,水流紊乱,流态较差,会不同程度地影响溢洪道的正常运行。该文根据广东省部分水库陡槽溢洪道水力模型试验研究成果,介绍改善溢洪道泄槽弯道段流态的断面超高、斜向高低坎、纵向导流墙、阶梯跌坎、弯道前设置消力池等工程措施,并对各种工程措施的适用性进行分析,研究成果可供类似工程设计和运行参考。When the bend of the spillway discharge chute is discharged,the horizontal shock wave is generated easily in the bend section,causing discharge turbulence and poor flow regime,which will affect the normal operation of the spillway in different degrees.Based on the results of hydraulic model test of some reservoir chute spillways in Guangdong Province in this paper,the engineering measures to improve the flow regime of spillway bend section are introduced,such as the sectional superelevation,insequent high and low sill,longitudinal diversion wall,stepped drop sill and setting up stilling basin before the bend,and the applicability of various engineering measures is analyzed.The research results can be used as reference for similar engineering design and operation.
