基于Infoworks的排水管网集水区优化研究

Research on Optimization of Water Collection Area of Drainage Pipe Network Based on Hydraulic Model

本文利用Infoworks ICM建立排水模型,分别以以自动、自动结合手动划分集水区两种方式为研究方法,并结合实地勘察,从管网节点在暴雨条件下淹水情况的角度和管网超负荷的角度对比分析自动划分与自动结合手动划分集水区的模型运行结果。结果表明,自动结合手动划分集水区相对于自动划分集水区所建立的排水模型能更加准确的模拟现实情况,更具科学性,尤其是在排水模型精度要求比较高时,采用自动结合手动划分集水区的方式可使排水模型的分析与应用更符合真实运行状态。

This article uses Infoworks ICM to establish a drainage model, which is based on two methods of the automatic and automatically combining manual division of catchment areas, and combines field surveys, from the point of view of the situation of the flooding of the pipe network node in the rainstorm condition and the overload of the pipe network, compared the results of the model operation of the watershed by automatically divides and a automatically combining manual division of catchment areas. The results show that the drainage model established by automatically combining manually dividing the catchment area relative to the automatic distribution catchment area can more accurately simulate the actual situation and is more scientific, especially when the drainage model accuracy requirements are relatively high, the automatic combination manual is adopted. The way of dividing the catchment area can make the analysis and application of the drainage model more in line with the real operation status.
