非线性滑坡动力学特征及方法

The Characters of Nonlinear Dynamic Landslide and its Methods

滑坡孕育过程的复杂形式取决于系统内部的非线性动力学特征,在外部条件诱发下,滑坡的形成表现为突变机制,在内部随机扰动下,滑坡过程既可走向混沌状态,又可趋于自组织临界状态,其最终演化道路取决于系统中正反馈机制的强弱程度,在此基础上,阐述了滑坡非线性研究的多种方法.

The complicated process of landslide development is derived from the properi-ties of nonlinear dynamics inside landslide systems. On the external condition, the occurnce of landslide manifests as caterstrophic mechanicism, while by internal and stochastic disturbance, the process of landslide can both tend to chaos state and e-volve into the state of self-organized criticity. The ultimate choice depends on the intensity of positive feedback in landslide systems. Based on this, variours methods for nonlinear research of landslide is described.
