复杂地质条件下堆积体边坡稳定性及其敏感性分析
Analyses of Stability and Sensitivity of Accumulation Body Slope under Complicated Geological Conditions
摘要
Abstract
The composition and geological structure of the collapse accumulation body of the Huashi cliff in Jinsha hydropower station are complex.In this paper,the collapse accumulation body is taken as the object of study;the parametric orthogonal test is adopted,and based on the limit equilibrium principle of rigid body, the sensitivities of slope safety factor to the cohesion coefficient and the internal friction angle of rock mechan-ics parameters are analyzed,which provide the basis for determining rock mechanical parameters.The stress 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.关键词
