【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】 To choose an jointed rock slope as study target,deformation features of the jointed rock slope under the action of strong earthquakes are analyzed by means of the discrete element method.Based on their nonlinear characters and the reconstruction theory of the phase space,it is proved that the evolution of the slope is a chaotic sequence,the dynamic failure of the slopes contains two bifurcations,and the stability failure of the slopes is essentially bifurcation.更多还原
