山区高等级公路不可避免地会频繁出现大填、大挖方路段,相伴而来出现了较多的高填方路堤边坡滑坡及路堑边坡坍塌等地质灾害现象。文章针对陵沁线杨寨河至西河底段K5+820～K6+120段高填方公路路堤的滑坡病害问题,在对现场实体工程调查的基础上,根据该滑坡的形态特征,分析了该滑坡的成因与机理;在此基础上,采用定性分析与理论计算相结合的方法,对边坡稳定性进行了分析评价,提出了相应经济、合理的边坡防护加固措施。
High-grade highways in mountainous areas inevitably frequently encounter large filling and large digging of road sections, accompanied by more geological disasters such as high-fill embankment slope landslide and cutting slope collapse. In this paper, based on the investigation of on-site physical engineering and based on the morphological characteristics of the landslide in the K5 + 820 ~ K6 + 120 section of the Yangzhahe-Xihe section of the Lingqin Line, On the basis of this, the method of combining qualitative analysis and theoretical calculation is used to analyze and evaluate the stability of slope and put forward corresponding economical and reasonable measures of slope protection and reinforcement.
