摘要
文章在分析广西南宁-友谊关高速公路宁明段膨胀土路堑边坡破坏原因的基础上,提出采用支撑渗沟为主,并辅以其它必要的综合措施的分割防护方案,论述了该方案在膨胀土地区的应用机理,并重点对方案的设计、施工工艺以及施工质量进行了阐述。
By analyzing the destructive reason of roadcut slope in Ningming Sec- tion of Nanning to Youyiguan Express- way,the paper proposes the splitting pro- tection method that mainly relies on sup- porting sewer and combines with other necessary integrated measures.It also il- lustrates the application mechanism for ex- pansive soil area,and highlights the scheme design,construction technology and quality control.
