斜坡稳定性是工程地质研究中的重点内容,常用的极限刚体平衡法难以考虑斜坡失稳机制中的非线性滑动特征,通过对斜坡模型演化方程控制变量的分析,结合运动方程,从系统结构上揭示了斜坡演化丰富的非线性动力学特征。研究表明:用奇异性理论根据斜坡演化的幅频响应特性,能够分析斜坡演化分叉现象;转迁集中的分叉点集构成的恰好是尖点突变的形式,充分揭示了斜坡失稳是内部结构变化与外部因素力量作用共同演化的结果。

Slope stability is the key study content of engineering geological, rigid body limit equilibrium method cannot consider nonlinear sliding characteristics of slope instability mechanism. Based on the control variables analysis of evolution equation of slope model, the paper reveals the rich nonlinear dynamical feature of evolution of slope combining motion equation. According to the amplitude-frequency response characteristics of evolution, its bifurcation phenomena with singularity theory was discussed. It fully revealed the slope instability which is the internal structure and external factors force coevolution of results.
