随着城市化进程的加快,逐渐建设更多的道路工程,近年来城市频繁出现暴雨积涝灾害,传统道路工程经常会出现雨水资源流失和排洪压力大的问题,不但会严重影响生态环境,也会导致损失生命财产安全,已经逐渐不能满足社会发展实际需求和生态保护规范。因此,国内提出了海绵城市的理念,并且依据低影响开发技术来保证合理控制导流雨水径流。本文主要分析了海绵城市理念在道路工程中的应用,以便于达到改善城市道路以及生态环境的目的。
With the accelerating process of urbanization, more road projects are being gradually built up. In recent years, frequent storm waterlogging and flood disasters have taken place in cities. Traditional road projects often suffer from heavy loss of drainage water resources and draining water. This will not only seriously affect the ecological environment, Will also lead to the loss of life and property safety, has gradually failed to meet the actual needs of social development and ecological protection norms. Therefore, the concept of sponge city was put forward in China, and based on the low-impact development technology to ensure a reasonable control of diversion storm runoff. This paper analyzes the sponge city concept in road engineering application, in order to achieve the purpose of improving urban roads and ecological environment.
