| 摘 要： | 提出了一种新型的海绵城市生物滞留沟(以下简称"生物滞留沟")结构,探求了雨水在该结构的下渗机理及雨水在路基中的分布情况。通过物理模型试验和数值分析方法,研究了具有包至卵石层顶的防渗膜的结构形式的生物滞留沟雨水下渗情况。结果表明:该结构形式具有极好的雨水收集效果,具备一定的雨水就地下渗功能,是一种符合海绵城市建设要求的结构形式。研究结果能够为海绵城市生物滞留沟设计提供一定参考。

| Abstract: | In order to study the effect of a novel bioretention swale with impermeable membrane covered up to pebble layer, physical model test and numerical analysis were used to investigate the infiltration mechanism of bioretention swale subject to different rain event. The results show that bioretention swale with such design feature has excellent rainwater collecting effect and rainwater can infiltrate into the surrounding soil simultaneously. It is concluded that bioretention swale with such design feature to be an ideal component that meets the requirements of sponge city construction and can provide a certain design reference in the sponge city. |
