基于Infoworks ICM的规划管网能力评估——以金鞭港地区为例

Evaluation of planning network capacity based on Infoworks ICM hydraulic model:taking Jinbiangang as an example

日益频繁的城市内涝给市民的出行带来了极大的不便,尤其是旧城区开发程度以及现状管网设计标准较低,甚至出现了逢雨必涝的现象,因此,对现状管网进行优化改造就显得尤为重要。文章以金鞭港地区的管网改造为例,采用Infoworks ICM模型和GIS技术对管网改造的效果进行评估,模拟不同重现期设计降雨条件下管网能力负荷以及出现内涝的区域,并给出优化建议。

In recent years, the increasingly frequent urban waterlogging has brought great inconvenience to the travel of citizens, especially the low development level of the old urban area and the current design standard of the pipe network,and the phenomenon of waterlogging in every rain. Therefore, it is very important to optimize the current pipeline network. This paper takes the reconstruction of pipe network in Jinbiangang as an example. Using the information works ICM model and GIS technology to evaluate the effect of pipe network reconstruction. Simulate the capacity load and waterlogging area of the pipeline network under different return period design rainfall conditions and puts forward optimization suggestions accordingly.
