摘　　要：道路雨水口泄流常以单篦雨水口为对象,缺少对多篦雨水口的研究。构建偏沟式雨水口三维水动力模型,利用Fluent对雨水口模型开展数值模拟实验,对雨水口水力特性进行计算分析。结果表明,雨水口入流均为堰流状态,多篦雨水口主要对侧面水流产生影响,随着入流量的增加,同种雨水口泄流效率无明显变化,多篦雨水口通过增大侧缘面积的方式扩大集水面积进而对泄流产生影响。结果可为城市雨水口布设提供新思路。The drainage of road rainwater outlet is often the object of single grate rainwater outlet,and there is a lack of research on multi-grate rainwater outlet.The three-dimensional hydrodynamic model of the rain-mouth was constructed,and the numerical simulation experiment of the rain-outlet model was carried out by Fluent,and the hydraulic characteristics of the rain-mouth were calculated and analyzed.The results show that the inlet flow of the rainwater outlet is all weir flow,and the multi-grate rainwater outlet mainly affects the side flow.With the increase of the inlet flow,the discharge efficiency of the same rainwater outlet has no obvious change,and the multi-grate rainwater outlet expands the water collection area by increasing the area of the side edge,thus affecting the discharge flow.The results can provide a new idea for the layout of urban rainwateroutlets.
