【摘要】 以节理岩质边坡作为研究对象,采用离散单元法,分析了边坡在地震作用下的变形特征,根据边坡演化过程中所表现出的非线性特征,应用相空间重构理论证明边坡的演化过程是混沌序列,边坡动力失稳过程包含2次分岔,边坡失稳的本质是分岔。更多还原

【Abstract】 Chooses the jointed rock slope as study target.By means of the discrete element method and the load-unload response model,features of deformation are analyzed.Based on their nonlinear characters and the reconstruction theory of phase space,it is proved that the evolution of slope is a chaotic process, the dynamic failure of slope contains two bifurcations and the stability failure of slopes is essentially bifurcation.更多还原
