| 摘 要： | 为了研究边坡岩体系统演化过程的非线性特征,一方面分析了边坡岩体系统演化过程的自组织特征;另一方面利用非线性动力学理论中的尖点突变理论模型和混沌动力学理论,建立了非线性动力学模型,分析了边坡岩体系统的演化过程,给出了边坡系统失稳的力学判据,表明了边坡岩体系统的非线性突变性,在演化过程中确实存在混沌现象。

| Abstract: | To demonstrate the nonlinear features of the evolutionary process of rockmass slope system,In this paper the self-organizing feature of the rockmass slope system is described firstly;Secondly,we establish a nonlinear dynamics model with the cusp catastrophe model and chaotic dynamics to analyze the evolution process of rockmass slope system.The mechanical criteria is obtained from the analysis,and the analisis also indicates that the rockmass slope system is of nonlinear mutagenicity and the chaos phenomenon really exists in the process of evolution. |
