武汉市二郎庙片区排水管网水动力模型分析

An Analysis of Hydrodynamic Model in Erlangmiao Area Drainage Network in Wuhan City

针对武汉市二郎庙片区排水管网现状存在的积水问题,使用InfoWorks CS软件对其管网系统进行水动力学建模。并利用建立的模型,模拟现有排水管网系统在不同降雨强度下出现的渍水状况,分析渍水形成的原因并找出管网系统中存在的瓶颈问题,以期为二郎庙片区排水系统改造提供辅助决策支持。

Aiming at the Erlangmiao Area Drainage Networks in Wuhan, Infoworks CS software is used to model hydrodynamics of its pipeline networks. The model considered waterlogging situation under different rainfall intensities in the drainage network system. The reasons for the formation of the waterlogging and main problem existing in pipe networks were simulated and analyzed. Based on the above results, the authors manage to find out the bottleneck of the drainage network system, and provide decision-making support for Erlangmiao Area drainage system reform.
