基于建模技术对城市排水防涝规划方案的探讨——以深圳市沙头角片区为例

Probe into urban drainage and waterlogging prevention plan based on modeling-case study on ShaTauKok district of Shenzhen

近些年来城市内涝频发,城市排水规划方案的制定已刻不容缓。介绍了建模软件MIKE URBAN的技术原理、参数选取及建模步骤。以深圳市沙头角片区作为规划实例,对现状管网进行评估以及风险区划分,在内涝分析的基础上制定规划方案,经方案优化后,确定最终规划方案。

Under the background of the frequent occurrence of urban waterlogging, it is necessary to establish the planning scheme of urban drainage. The planning scheme is technically based on the modeling software MIKE URBAN which is developed by Danish Hydraulic Institute （DHI）. Taking ShaTauKok area in Shenzhen for example, this paper describes the processes of making the final scheme of urban drainage, including evaluating the existing sewer network, finding out dangerous zones, analyzing the cause of flood and optimizing the scheme.
