武罐高速公路K129+100～+160右侧路堑边坡滑塌是单斜构造地区变质岩错落体局部变形失稳的典型代表。错落体局部失稳滑塌变形后不仅造成路堑边坡工程病害,而且对其相邻的青峪沟大桥存在一定的安全隐患。本文从错落体地质构造现背景入手,结合施工扰动和降水入渗综合作用的影响,对错落体前缘失稳变形破坏的机理进行了分析,在稳定性计算的基础上提出以坡体加固和坡面防水的综合处治措施,具有重要的现实指导意义。
The slump of the right side cut slope of K129 +100 ~ +160 of the caning expressway is a typical representative of the local deformation instability of the metamorphic rock massif in the monoclinic zone. After the partial failure of the landslide and the landslide, the landslide deformation and deformation not only cause the engineering defects of the cutting slope, but also have potential safety hazard to the adjacent Qingyugou Bridge. This paper starts from the background of the geological structure of the patchy body and analyzes the mechanism of the deformation and failure of the front of the patch body based on the combined action of construction disturbance and rainfall infiltration. Based on the stability calculation, Comprehensive treatment of slope waterproofing has important practical significance.
