高速公路膨胀土路堑坍滑原因分析

Analysis of the reasons for the landslide of expansive soil cutting slope in expressway construction

结合实际工程中所遇到的膨胀土滑坡问题,分析了导致高速公路膨胀土路堑边坡多次发生坍滑的主要原因,在进一步补充勘查的基础上,对该段膨胀土路堑滑坡治理的设计作了相应的修改,使滑坡问题得以解决,为工程的安全运营提供了保障。

According to the landslide of expansive soil slope occurring in the practical engineering, the main reasons for the frequent collapse of expansive soil cutting slope in the expressway are analyzed. Based on the information of survey further supplemented, the corresponding modifications to the design in the treatment of landslide in the expansive soil cut mentioned in this paper are made, which solves the problem of landslide and guarantee the safety of engineering construction.
