某浅层边坡的加固变更专项方案设计

Special scheme design for reinforcement and modification of a shallow slope

重点介绍广东省仁博高速K438+320～K438+890路堑右侧边坡加固变更专项方案。原设计边坡出现2段滑塌,分析了滑坡形成原因,并结合地勘钻孔及现场调绘对该段边坡重新进行分区设计,采用抗滑桩及锚索锚杆加固等方式,保证边坡滑坡被有效处理。

The paper focuses on the special plan for the reinforcement of the right side slope of the K438+320~K438+890road in Renbo Expressway,Guangdong Province.There are two stages of slopes in the original design slope.Now,the reasons for the formation of the landslide are analyzed.Combined with the geological prospecting and on-site mapping,the slope of this section is re-zoned,and the anti-slide piles and anchor bolts are used to ensure the side.The slope landslide is effectively treated.
