基于模型的城市雨水系统改造规划方法——以北京奥林匹克公园地区为例

Model-based method of rebuilding the urban drainage system:a case study of Beijing Olympic Green region

针对城市雨水系统的改造问题,分析了其改造的可能方式;在此分析的基础上,提出了基于模型的城市雨水系统改造规划的编制方法,该方法主要包括:城市雨水系统模型建立、雨水系统改造标准确定、现状雨水管道最大排水能力分析、雨水系统改造工程方案和实施效果评估;最后,以北京奥运奥林匹园地区为例进行了雨水系统改造的案例分析。

To investigate the problems in rebuilding of the urban storm water drainage system, this article analyzes the possible approaches for rebuilding the drainage system, and proposes the methods of planning the model-based urban storm water drainage system, which include： building the urban storm water drainage model, determining the rebuilding standard, analyzing the maximal capacity of the current storm water drainage system, assessing the rebuilding plan and the effect of the implementatiorL At last, it analyzes a case study of rebuilding storm water drainage system in the region of Beijing Olympic Green.
