- 摘要:
- 城市内涝的成因错综复杂，要准确分析并提出合理的解决方案，应全局把握整个排涝分区降雨全过程的水位、流量动态。以南昌市红谷滩中心区排涝分区为研究对象，采用MIKE系列水力模拟软件建立耦合模型，以50年一遇24 h降雨时间序列曲线作为降雨边界条件进行模拟分析，得出内涝风险评估结果，根据评估结果分析得出内涝原因，并结合海绵城市设计理念提出相应的解决方案。同时引入海绵城市设计理念，将城市立交桥周边难以开发的用地设计为下凹式绿地，结果表明，该措施可有效缓解电排站压力。
- Abstract:
- The causes of waterlogging are complicated. In order to accurately analyze the causes and propose a reasonable solution, the water level and flow rate of the whole process of rainfall in the whole drainage area should be comprehended. The article took the central area of Honggutan in Nanchang City as the research object, MIKE series hydraulic simulation software was used to establish the coupling model. And furthermore, the rainfall time series curve of every 24 hours in 50 years was adopted as the rainfall boundary condition. Then the assessment results from the above simulation results were obtained. Finally, the solution of waterlogging was proposed according to the causes. Combined with the concept of sponge city design, the corresponding solutions were put forward. In the solution, some of the land under city overpass was designed as sunken lawn to further expand the water storage, which could effectively relieve the pressure of the power station.
