摘要
下沉式绿化带是海绵城市建设理念在道路设计中的具体体现,目前在国内LID系统中已被广泛采用,但是该技术对道路结构使用性能的影响目前还没有系统研究。采用芝加哥降雨模型,给定降雨重现期与降雨历时等参数,基于Biot理论,研究非饱和道路结构在降雨时侧向渗流问题。
The sinking-mode greenbelt is a concrete embodiment of the concept of sponge city which used in the road design, it has been widely used in the system of LID in domestic, but the influence of this technology on service performance of the road structure is short of systematic research. This article researched the lateral seepage of the road structure, which based on the theory of Biot and using the Chicago rainfall model under given repetition period of rainfall and the duration.
