摘要
以SWMM模型为模拟平台,建立研究区城市排水防涝系统联合评价体系。以基础信息平台为基础,结合不同重现期降雨过程对研究区排水防涝系统进行模拟分析,分析在不同重现期设计暴雨下,排水管网的承载能力、积水面积、易积水点、积水深度及积水时间等,并给出内涝易发区缓解措施,以期对制定防汛抢险预案提供科学依据。研究中所使用的模拟方法具有一定的通用性,可供其他城市排水防涝系统能力评估时参考。
The study regards SWMM model as the simulation platform to establish the joint evaluation system for urban draining and prevent waterlogging system in the research area.Based on the basic information platform,the study analyzed the drains system simulation in the studied area combining different return period rainfall processes.It analyzes the bearing capacity of the drainage pipe networks,water area,easy seeper point,water depth and water retention time under different return periods of design storms,and the urban flood control measures is given,In order to provide scientific evidence for flood control and emergency rescue plans.The simulation method in the study has a certain level of universality,so it can be used in other cities.
