膨胀土地区边坡的排水和防护设计

The Drainage and Protective Design of the Highway Slope in Swelling Soil Area

以海南西线高速公路通过膨胀土地区的边坡为例,介绍膨胀土地区高等级公路边坡的排水和防护设计,边坡(路堤、路堑)的排水和防护设计及做法,根据不同的土质情况,采用的排水和防护设计的效果进行了评析,总结膨胀土地区利于边坡稳定的排水和防护设计及进行不同的处理方法,为今后类似工程提供参考。

Taking the slopes in swelling soil area on the west line of Hainan Express Highway as an example, this paper introduces the drainage and protective design of the slopes of high grade highways in swelling soil area, as well as the drainage, protective design and practice of slopes (embankment and road cutting). According to different soil status, this paper analyzes the effect of the adopted drainage and protective design and summarizes the drainage and protective design facilitating the stability of slopes in swelling soil area and different ways of treatment, providing reference for similar construction in the future.
