公路边坡挡土墙注浆加固技术探讨

Highway Retaining Wall Grouting Technology of Slope

随着高速公路运营时间增长,边坡结构物病害也不断显现。通过某工程实例,说明对部分岩体或砂性土边坡挡土墙开裂、外倾等病害用压力注水泥浆体进行维修加固具有较好的效果。在加固边坡挡土墙等结构物的同时对后方土体也具有一定的改良复合作用,能有效提高坡脚抗压能力,消除坡脚应力集中的影响。

With the growth of the highway service time, the slope structures diseases also appear constantly. A project example is investigated to illustrate that using compressed cement paste to maintain and strengthen the cracking or extraversion of rock or sandy soil slope retaining walls has good effect. It can not only strengthen the retaining walls and other structures, hut also has some improved composite role on the soil, effectively improving the toe compression capability and eliminating toe stress concentration.
