含弱层边坡稳定性影响因素敏感性分析
Analysis on influencing factors sensitivity of slopes stability with weak layers
摘要
Abstract
In order to study the sensitivity of influencing factors of slope stability with weak layer,the main influencing factors of slope stability with weak layer are determined based on theoretical analysis,and the stability coefficient of weak layer slope under the influence of multiple factors is analyzed by orthogonal range analysis.The results show that the main factors influencing the stability of the slope with weak layer are the action of water body,the parameters of the weak layer and the geometric structure of the slope.The water content is inversely proportional to the mechanical index of weak layer.With water content increasing,the decrease range of weak layer cohesion and internal friction angle is obvious.The sensitivity order of quantifiable influencing factors is weak layer internal friction angle＞weak dip angle＞slope angle＞groundwater level＞weak layer cohesion.关键词
