论海绵城市道路优化设计

Discussion On The Optimum Design Of The Road In The Sponge City

近年来,我国城市暴雨积涝灾害频发,而传统城市道路普遍存在排洪压力大、雨水资源流失等问题,不仅给生态环境带来了极大的危害,也给人们造成了严重的生命财产损失,这种现象如今已经无法满足生态保护和社会发展的需求。为此,我国提出了"海绵城市"的概念,采用LID(低影响开发)技术和设施来进行雨水径流控制。本论文研究海绵城市理念下的城市道路系统设计,以期改善城市道路和生态环境。

During recent years, the rainstorm disasters in our country occurred frequently and the traditional city road exists drainage pressure, rainwater resource loss and other problems. The damage not only brings to the eco- logical environment but also caused a serious loss of life and property. It has been unable to meet the needs of so- cial development and ecological protection. Therefore, the concept of ＂sponge city＂ is put forward in China and the LID （low impact development） technology and facilities are used to control the rain runoff. This paper studies the urban road system design under the concept of sponge City in order to improve the ecological environment of urban road.
