摘要
以南昌市青山湖排涝片为研究区域;设置不同重现期的降雨量、不同的最低调蓄区控制水位等雨洪情景,并应用MIKE软件模拟不同雨洪情景下的排涝进程;通过对泵站开机负荷、主要控制断面水位、流量等统计参数的对比,分析不同雨洪情景对市政排水与城市排涝系统的影响,进而提出城市排涝系统的雨洪联合调度策略:设定不同降雨条件下的河湖水位控制时机与阈值,建立健全降雨集中期的机组应急调度规程,从而有效削减雨洪峰值,最大限度地发挥内涝防治系统的既有功能。
Under rainwater and flood scenarios,which include the rainfall under different repetition period and the different lowest control water level of conditioning storage area,MIKE is used to simulate the drainage process of Qingshanhu drainage area(a zone in the central city of Nanchang).Based on the comparison of the statistical parameters such as the load of the pumping station,the water level and flow of the main control section,this paper analyzes the influence of the municipal drainage and urban drainage system under different rainwater and flood scenarios,and puts forward the joint scheduling strategy of the urban drainage system,which includes setting the time and threshold of water level under different rainfall conditions,establishing and improving the emergency operation rules of pumps,so as to effectively reduce the peak value of flood level,and maximize the existing functions of the waterlogging control system.
