基于水力模型的雨水排水系统改造方案

Upgrading Scheme of Rainwater Drainage System Based on Hydraulic Model

利用InfoWorks ICM软件建立上海市某雨水排水系统模型,根据模拟结果得知排水系统积水原因为排水系统下游总管输水能力不足,上游管道顶托。据此确定系统改造方案,并利用模型软件对方案做进一步优化和校核。另外,与传统水力计算方法相比,经模型优化后的改造方案具有更好的针对性和经济性,可直观展示系统改造后的排水效果。

A rainwater drainage system model in Shanghai was established using InfoWorks ICM software.According to the simulation results,the surcharging of the drainage system was the consequence of the insufficient drainage capacity of the downstream sewers.The upgrading scheme was optimized and validated in the model.In comparison with the schemes derived from traditional hydraulic calculations,the upgrading scheme optimized by the hydraulic model was more pertinent and economical,and could intuitionally demonstrate the effect of drainage after optimizing of the system.
