摘要
该文对京沪高速公路（化—临段）某路堑边坡软弱夹层的加固全过程进行了详细介绍。并在对工程地质情况调查的基础上，进行了严密的理论计算，确定了设计方案，实施过程中采用了一项专有技术──“单孔分层多次高压注浆技术”加固了软弱夹层，注浆的同时安装了抗剪锚杆，实现了“锚”和“注”的结合，工程取得成功。
The paper introduces minutely the whole process of the soft intercalation solidification of a cut slop of Beijing- Shanghai freeway(Hua - Lin section). Also, on the basis of investigating the engineering geological conditions, the rigorous theoretical computation is made and the design scheme is determined. During the process of implementation, a special technique 'single hole layering multiple high pressure grouting technique'is adopted to solidify the soft intercalation, and the anti - shear anchor rod is installed simultaneously, which realizes the combination of anchor rod with grouting, and yields positive success of the project.
