摘　　要：随着城市水环境整治项目的实施与推广,河网水系连通在水量调蓄、河道自我修复等方面发挥着重要作用,因此不同工况下调度运行洪水水位显得尤为重要。以佛山乐平镇水系连通工程为例,通过MIKE模型建立工况模拟,分析大同湖在不同工况下的防洪水位和防洪效果。结果表明,大同湖建设有利于片区防洪,结合防洪排涝调度能够保障周边区域的防洪排涝安全;在10年一遇1d排干的标准和现状排涝条件下,大同湖能降低洪水水位0.897m,防洪排涝效益明显。该项目可为类似水系连通工程防洪水位的计算分析提供借鉴。With the implementation and promotion of the urban water environment improvement project,the river network connection played an important role in water regulating and storing and channel self-repairing.Taken the Leping River System Connection Project in Foshan as an example,this paper analyzes the flood control level and flood control effect of Datong Lake under different working conditions by using Mike Model.The results show that the Datong Lake was favorable for flood control in the area,combined with the flood control and drainage operation in the area,the safety of flood control and drainage in the surrounding area could be guaranteed.Under the standard of one-in-one-day drainage in 10 years and the present condition of drainage,the water level of Datong Lake was reduced by 0.897m,and the benefit of flood control and drainage was obvious.At the same time,it can provide some reference and reference for the calculation and analysis of flood control level of similar water system connection project.
