【摘要】：以某县排水系统规划设计为研究对象,利用Info Works ICM软件建立排水系统水力模型,对排水管网的非恒定流进行仿真模拟,并利用水力模型对城市内涝风险进行评估分析,得到城市各区域的内涝综合风险指数。结果表明,旧城区排水分区为内涝风险较高区域,应对其进行雨水系统的重点改造。
[Abstract]:Taking the planning and design of drainage system in a county as the research object, the hydraulic model of drainage system is established by using Info Works ICM software, and the unsteady flow of drainage pipe network is simulated, and the risk of urban waterlogging is evaluated and analyzed by hydraulic model. The comprehensive risk index of waterlogging in various urban areas is obtained. The results show that the drainage zone of the old urban area is a region with higher waterlogging risk, and the emphasis of Rain Water system should be carried out on it.
