【摘要】 顺层边坡位移对其稳定性有着重要的控制作用.目前顺层边坡演化过程中位移效应对稳定性的影响研究很少,深入研究顺层边坡位移与稳定性的关系能为边坡稳定性分析和治理提供重要依据.通过对摩擦定律的状态分析,研究顺层边坡演化的内在机制.根据平面摩擦行为,建立边坡动态稳定性分析模型,并从模型的动力学特点出发,建立运动学微分方程.对微分方程进行系统的非线性动力学分析研究,探讨位移效应对边坡稳定性的影响.更多还原

【Abstract】 The displacement of bedding edge slope plays an important part in controlling its stability.However,at present there are few research on the influence of displacement effect in the evolution process of bedding edge slope on its stability.Therefore,an in-depth study of the relationship of its stability to its displacement can provide a significant basis for its stability analysis and harnessing.By means of state analysis of friction law,the inherent mechanism of evolution of bedding edge was investigated.According to behavior,a model was set up for dynamic stability analysis of edge slope,and its kinematic differential equation was established.By means of analysis and study of nonlinear dynamic behavior of this differential equation,the influence of displacement effect on stability of edge slope was explored.更多还原
