基于低影响开发模式的高速公路海绵化设计研究

Sponge Design and Study of Highway Based on Low Impact Development

为解决高速公路雨水控制与合理利用的问题,采用雨水水量平衡计算和水质净化相结合的分析方法,以南宁吴圩机场第二高速公路海绵化设计为例,研究了低影响开发建设理念在高速公路海绵化设计中的应用。通过分析高速公路沿线地形地貌,结合高速公路使用功能、行车安全等因素,因地制宜设置海绵措施,从而达到削减径流污染、减少高速公路工程建设对周边环境影响、实现雨水资源化利用的目的。

In order to solve the problems of highway rainwater control and reasonable using,analytical method combining rainwater balance calculation and water quality purification is adopted.This paper takes the sponge design of the 2 ndhighway of Nanning Wuxu Airport as an example,and introduces the application of low impact development in highwaysponge design.Bythe analysis of topography along the highway,spongemeasures should be set according to function of use and traffic safety of highway and local conditions so as to achieve the goal of reducing runoff pollutionand impact of contruction on surroundings and rainwater resource utilization.
