层状反倾岩质边坡影响因素及反倾条件分析

Analysis on influential factors and toppling conditions of toppling rock slope

摘要: 借助广西龙滩水电站左岸边坡工程地质剖面模型以及岩体参数对反倾岩质边坡的影响因素进行了多工况分析,提出了边坡反倾优势角的范围。并通过不同模型对应同一点的位移矢量角对层状反倾岩质边坡的反倾条件进行了界定分析。通过与工程实例总结资料对比,其可用性强,并为反倾岩质边坡的快速破坏模式分析提供了科学依据。

Abstract: Based on the engineering geologic section model and rock mass parameter of left bank slope of Longtan Hydropower Station,the influential factors were analyzed with orthogonal analysis of toppling rock slope,the range of dominance of toppling slope,was proposed and the topping condition with displacement vector angle in the same nod of different models were also analyzed.Through contrast with the practical engineering case,the obtained results were shown to be applicable as a quick analysis method for failure mode of toppling rock slope.
