摘　　要：以白洋淀分汊河流双泄水建筑物为例,通过模型试验先单独确定泄洪闸、溢流堰不考虑相互影响下的水位—泄量关系,再通过数值模拟考虑二者之间的相互影响,确定二者相互影响下能否达到设计效果,探索出模型试验与数值模拟相结合确定分汊河道分流比及泄流能力的方法。通过这种方法,得到了泄洪闸溢流堰的分流比及闸下、堰下水位,并与设计值进行比较,发现其差异很小,差异均在6%以内,表明泄洪闸、溢流堰设计泄流能力基本满足要求。Taking double-discharge building in branching stream of Baiyang Lake as an example,the relationship between water level and discharge capacity of only spillway gate and overflow weir was determined by model test,and then the mutual influence between them was determined by numerical simulation.The method of combined model test and numerical simulation to determine the diversion ratio and discharge capacity were explored.Through this method,the diversion ratio of the spillway gate and the overflow weir and the water level under the gate and weir were obtained.Compared with the design value,the difference is very small within 6%.The results show that the discharge capacity of the spillway gate and overflow weir mainly meet the requirements.
