摘要: 排水效果评估是海绵城市建设的必要环节,城市雨洪模型则是评估工作的重要支撑工具。以北京市某小区为例,基于一二维耦合的城市雨洪模型构建了研究区域精细化排水模型,模拟分析了海绵化改造方案实施前后小区降雨径流、排水和地表积水等要素的变化情况。结果表明构建的排水模型可以较好地反映小区排水现状,拟定的排水系统海绵化升级改造方案可以有效地改善研究区域的排水情况,管网溢流和地表积水情况明显减少。研究结果可为排水小区管网水力状况数值分析及海绵城市建设与管理提供一定的技术参考。

Abstract: Drainage effect evaluation is a necessary links in the construction of Sponge City,and urban rainfall mathematical models are important supporting tools for the evaluation work.Taking a residential area in Beijing City as an example,a refined drainage model of the study area was constructed based on a coupled 1D and 2D hydrodynamic model for urban rainstorms,and the drainage situation before and after the sponge transformation of the drainage system were simulated and analyzed.The results showed that the constructed model can well reflect the real drainage situation of the community,and the proposed drainage system upgrade plan can effectively improve the drainage capacity in the area,and the overflow and submergence were significantly reduced.The research can provide some technical reference for the simulation of the hydraulic condition of drainage community and the construction and management of Sponge City.

Key words: SWMM model, drainage system, Sponge City, coupled 1D and 2D hydrodynamic model
