摘要
金沙水电站花石崖崩塌堆积体组成成分和地质结构复杂,本文以崩塌堆积体为研究对象,采用参数正交试验,基于刚体极限平衡原理,分析了边坡安全系数对岩石力学参数凝聚系数c和内摩擦角φ的敏感性,为确定岩石力学参数提供依据;利用基于有限元法的软件ABAQUS计算崩塌堆积体的应力及变形,确定其危险滑动面,为稳定性分析提供计算剖面.
The composition and geo Jinsha hydropower station are ogical structure of the collapse accumulation body of the Huashi cliff in ex. In this paper, the collapse accumulation body is taken as the object of and deformation of the collapsed accumulation body are calculated by the software ABAQUS based on the fi nite element method; and the dangerous slip surface is determined, which provides the calculation section for the stability analysis.
