基于海绵城市理论的地下水库工程设计

为构建以城市水系统为核心的海绵城市系统治理工程,在总结当前海绵城市建设存在的问题基础上,提出了应用地下水库系统工程作为城市海绵体的海绵城市建设思路。基于海绵城市理论建立了以7大系统为配套工程、囊括“渗、滞、蓄、净、用、排”等措施的地下水库系统工程整体架构,得出了以地下水库工程为主导的海绵城市水循环路径,成功构建了以城市水系统为核心的海绵城市系统治理工程,对增强城市防洪涝能力、高效利用水资源、修复城市水生态环境具有显著效益。本地下水库系统工程设计为海绵城市建设提供了切实可行的水工程技术支撑和行之有效的良性水循环保障体系。

Engineering Design of Underground Reservoir Based on Sponge City Theory

On the basis of summing up problems in current construction of sponge city, an idea of sponge city construction with underground reservoir system as city sponge is put forward. In line with the theory of sponge city, the holistic structure of underground reservoir system is described with seven systems as supporting project involving seepage, stagnation, storage, net, use, and discharge. The water circulation path of sponge city is dominated by such underground reservoir system. The sponge city project with urban water system as its core is of evident benefit for improvement of flood and water-logging control capacity, efficient utilization of water resources, and restoration of urban water ecological environment. The research provides a feasible technical support and effective guarantee of sound water circulation for sponge city construction.
