Study on the Design of Hedge Lane in Long Downslope Section of Mountainous Expressway

山区高速公路设置避险车道能有效提高道路交通的安全性,依托二连浩特至广州高速公路粤境连州三水至怀集怀城长大下坡路段的避险车道设计实例,结合国内外相关资料文献,对山区高速公路长大下坡路段避险车道的设计原则、设计内容和设计方法进行了研究。

Setting up hedge lanes of mountain expressway can effectiveely improve the safety of road traffic.Based on the design examples of hedge lane in the long downhill section from Lianzhou Sanshui to Huaiji Huaicheng in Erlianhaote-Guangzhou expressway in Guangdong,design principles,contents and methods of hedge lanes in the long downhill of mountainous expressway have been researched with the relevant documents at home and abroad.
