摘　　要：公路路面径流中含有120多种污染物,对地表受纳水体会造成严重污染。如何避免或减轻路面径流对沿线水体造成的污染,是公路建设中必须考虑和需要解决的重大环保问题。文中结合我国地表水环境质量标准,对路面径流中的主要污染物净化要求和排放标准进行了研究,基于生态环保和方便可行的原则,提出了路面径流主要渗滤介质的选择方案;在分析渗滤介质对路面径流净化处理效果的基础上,建立了路面径流渗滤排水系统设计模型。最后结合公路建设实际,研究了高路堤、深路堑一侧的渗滤系统设计方法,提出了依托生态种植槽和排水涵洞的路面径流渗滤系统设计方案,为水环境敏感区的公路建设提供了技术指导和参考。Road runoff contains more than 120 kinds of contaminants which will cause serious pollution to the receiving water. How to avoid or reduce the pollution caused by runoff is a major environmental problem in the highway construction. The removal requirements and emission standards of the main road runoff pollution are studied combining the Surface Water Quality Standards of China. Based on the principle of a viable and convenient environmental protection, the main alternatives of runoff infiltration medium are proposed. The runoff infiltration drainage system design model is established based on the analysis of the purifying effect of runoff infiltration medium. Combining the reality of road construction, the design method of filtration system in high embankment and deep cut side is studied, and the road runoff percolation system designs based on ecological cultivation tank and drainage culverts is worked out. The research can provide technical guidance and reference for the road constructions in water environmentally sensitive areas.
