市政道路低影响开发设施设计案例分析

Case Study of Low Impact Development Facilities for Municipal Roads

市政道路的低影响开发设施是海绵城市建设的主要内容。结合设计经验总结了市政道路低影响开发设施的设计要点。介绍了深圳市登良路、江西省弋阳县江廖肖村旅游入口公路和陕西省汉中丝绸之路的低影响开发设施设计案例,利用暴雨管理模型分析了这些道路低影响开发设施的滞留暴雨径流的效果。重点分析了江廖肖村旅游入口公路低影响开发设施的设计方案和抵抗不同降雨的效果。从方案设计、模型模拟、技术措施等方面总结了道路低影响开发设施设计本土化过程中的工程经验。

The low impact development （LID） facilities for municipal roads are the important components for the sponge city construction in China. The design requirements of the LID facilities for municipal roads were summarized on the basis of design experience. The design cases of the LID facilities for the Dengliang Road in Shenzhen, the Tourist Entrance Road in Jiangliaoxiao Village, Yiyang County, Jiangxi Province and the Silk Road in Hanzhong City, Shaanxi Province were introduced. The efficiency of the LID facilities for retention of stormwater runoff was simulated using SWMM. The design scheme and flood control effects of the LID facilities along the Tourist Entrance Road were analyzed. The experi- ence how to better design the LID facilities was outlined from viewpoints of design scheme, hydrological model simulation, technical measures.
