城市地下空间低影响开发雨水系统设计

Rainwater System Design of Underground Space in Cities Based on Low Impact Development Concept

针对日益突出的城市雨水问题,基于低影响开发理念,结合我国国情,对城市地下空间开发所涉及的雨水处置问题进行了研究。侧重介绍地面构造对雨水入渗的促进措施、壤中流蓄排技术及地下建筑主体的防渗设计。

The paper probes into the issues of dealing with rainwater in the urban underground space construction,based on the low-impact development concept,and combining with the current situation of China.Then,authors emphasize the promotion measures of covering earth structure to rain infiltration,the technology of storm-water drainage in soil,and impermeable design of the main body of underground space.
