公路膨胀土路堑边坡的破坏特征及勘察技术探讨

摘要

膨胀土因其地质特性而容易造成路堑边坡的滑坡破坏。通过研究膨胀土路堑边坡胀缩活动带的变形活动特点和滑坡破坏规律，探讨其相关的勘察技术。%Its geological characteristics of expansive soil is likely to cause landslides cutting slope of destruction. By studying the expansive soil slope Events expansion and contraction characteristics and laws of deformation bands landslide destroyed, and explore the related survey techniques.
