发布时间:2019-02-22 09:01
【摘要】:基于野外地质勘查、现场监测及数值计算,对凯(里)羊(甲)高速公路RK9滑坡地质条件、形成机制、治理措施进行分析。结果表明:该滑坡为大型牵引式顺层滑坡,平面形态具有二级滑动特征;滑坡变形最大值为5 673.3 mm,变形主要集中在暴雨期;引发滑坡的主要因素为降雨及工程活动;采用清方、坡面防护、抗滑桩加固、综合排水等措施对滑坡进行综合处治,效果良好。
[Abstract]:Based on field geological exploration, field monitoring and numerical calculation, the geological conditions, formation mechanism and control measures of RK9 landslide in Kai (Li) Yang (A) Expressway are analyzed. The results show that the landslide is a large towed bedding landslide with second-order sliding characteristics in plane form, the maximum deformation of landslide is 5 673.3 mm, and the main factors causing landslide are rainfall and engineering activity. Measures such as Qingfang, slope surface protection, anti-slide pile reinforcement and comprehensive drainage are adopted to treat landslide comprehensively, and the effect is good.
