南昌高新湖西片区积水问题分析及初步解决方案

Analysis and Preliminary Solution on Waterlogging Problems in Huxi Area of Nanchang High-tech Development Zone

以南昌市高新区湖西片区为例,根据区域降雨及地形资料,以及一个实例,讲述如何根据研究区域的降雨资料、地理地形数据、排水系统数据,利用专业的动态耦合模拟系统,模拟排水管网、明渠、河道、各种水工构筑物,以及二维坡面水的流态,直观地表达地面径流和管网排水状况,找出积水原因和内涝点,并提出相应的解决方案。该模拟还能认证实施后的效果。

Taking Huxi Area of Nanchang High-tech Development Zone as an example,based on the regional rainfall and terrain data as well as an example,according to the rainfall data,topographic data and drainage system data of the studied area,the professional dynamic coupling simulation system is used to simulate the drainage pipeline network,open channel,river,each hydraulic structure and the flow state of two-dimensional slope water,which can intuitively express the surface runoff and pipeline network drainage conditions,and find out the waterlogging causes and points.The relevant solution is proposed.This simulation can also approve the effect after implemented.
