基于低冲击开发模式的美国城市道路雨洪管理实践与借鉴

The Practice and Reference of Low Impact Development in American Road Rainwater Management Design

从城市道路雨洪管理的角度出发,概述美国道路雨洪管理中低冲击开发的发展演化,详述美国道路的低冲击开发核心工程技术,结合这些技术在道路雨洪管理中的实践,得出不同城市功能区道路的低冲击开发设计应用形式。从道路现状的利用、技术组合的拓展和渗水面积的扩大3个层面浅析低冲击开发模式对我国道路雨洪管理的启示。

From the perspective of urban road rainwater management, the development of LID in American urban road rainwater management was reviewed. Then, through analyzing the five core technical projects of LID and their practices in American road rainwater management, it was concluded that there are different forms in different urban functions. The use of LID in Chinese urban road rainwater management was explored from three aspects, including the usage of road condition, the exploration of techniques and the expansion of area for seepage.
