摘要
陡峻山区展线的道路开挖过程中,易诱发自身基本稳定的坡体发生变形和滑移,对施工和人员安全有极大影响,因此有必要研究错落体发育的工程地质条件、规模特征及破坏模式,评价其稳定性及变形趋势.本文以四川盆地西南部山区某地公路修建过程中遇到的错落体为例,查明了错落体的规模、地层特征及破坏模式等.该错落体整体基本稳定,但在强震工况下易发生局部滑塌,考虑到该错落体位于陡峻坡体的中上部,变形滑塌会对山体下部施工和过往人员威胁巨大.
Abstract
In the process of road excavation of the steep mountainous area,it is easy to induce the deformation and slide of the slope,which has a great impact on the construction and personnel safety.It is necessary to study the engineering geological conditions,scale characteristics and failure modes of the development of the staggered body,and to evaluate its stability and deformation trend.This paper took the staggered landslides encountered in the construction of a certain place in the southwestern mountains of the Sichuan Basin as an example,and identified the scale,stratigraphic characteristics and failure modes of the staggered landslides.Considering that the staggered body is located in the middle and upper part of the steep slope,the deformation and collapse will pose a huge threat to the construction of the lower part of the mountain and the passing personnel.
