摘要
在对西南山区某顺层白云岩边坡进行资料收集和现场调查的基础上,通过赤平投影法对顺层白云岩边坡稳定性进行了分析,确定了边坡的稳定性和边坡的滑移类型;深入分析了影响边坡稳定性的主要因素;采用极限平衡法计算了边坡的安全系数。通过对滑面强度、滑体密度等参数的敏感性分析发现,抗剪强度参数对边坡的稳定性影响较为敏感。其成果可为今后类似边坡的稳定性分析和加固设计提供参考。
The slope stability and slip type of bedding dolomite slope determined by the stereographic method, based on detailed data collection and field investigation of bedding dolomite slope in a mountainous area of southwest China. This paper offered a deep analysis on the main factors which influence the slope stability adversely. It also applied the limit equilibrium method to calculate the safety coefficient of the slope factor. The sensitive analysis of the strength parameters and landslide density parameters revealed that shear strength parameters may have a more sensitive impact on slope stability. The study could serve as a foundation for the next phase of reinforced design and construction.
