- 摘要:
- 针对西北地区雨洪调蓄特征，在排涝分区层面建立雨水调蓄空间评估模型，研究雨水调蓄设施布局及规模对排水系统防涝能力的影响。模拟结果表明，在常规汇水面积（约2.5 km2）条件下，雨水调蓄设施规模控制在1 500 m3较为经济合理，可以有效削减径流峰值流量、延缓出流时间。与集中在末端设置调蓄设施相比，中途设置500 m3、末端设置1 000 m3的布局方式更为合理，能够削减10.7%的径流峰值流量，并将系统重现期从20年一遇提高至100年一遇，同时可以减小下游管段的管径，节省投资。实践表明，雨水调蓄设施可以与公园绿地融合，实现“平急两用”。
- Abstract:
- In view of the rainfall-runoff regulation characteristics in Northwest China, a spatial assessment model for rainwater storage facilities was established at the drainage zoning level to investigate the effects of facility layout and scale on the flood control capacity of the drainage system. Simulation results showed that, for a conventional catchment area of about 2.5 km2, a storage volume of 1 500 m3 was economically reasonable and effective in reducing peak runoff flow and delaying outflow time. Compared with a centralized configuration with all storage facilities placed at the terminal end of the pipeline network, a distributed layout—with 500 m3 installed midway and 1 000 m3 at the terminal—proved to be more rational. This distributed arrangement could reduce the peak runoff flow by 10.7% and upgrade the system’s design storm return period from a 20-year event to a 100-year event, while also allowing for a reduction in the diameter of downstream pipe sections and thereby lowering construction costs. Practical applications demonstrated that rainwater storage facilities could be integrated with park green spaces, thereby achieving the goal of “dual use in normal and emergency situations”.
