软土地基上匝道路堤裂缝的处治方案设计

Treatment Scheme for Ramp Embankment Crack on the Soft Ground

针对在软土地基上修筑高速公路常出现路堤开裂问题,根据某高速公路立交匝道路堤的监测资料,探讨软土地基上路堤裂缝的成因,介绍了采用袖阀管注浆、旋喷桩等方法综合处治路堤裂缝的设计方案。

There are some embankment crack problems when building expressway on the soft ground. The cause of interchange ramp embankment crack was discussed according to monitor data, and the synthetic treatment scheme for embankment diseases with sleeve-valve pipe grouting technology and jet grouting was introduced in this paper. It is essential to use dynamic monitor and synthetic treatment for engineering diseases.
