摘要
根据耗散结构形成和维持的三个条件 ,从宏观和微观两个方面研究了岩体变形系统的非线性特征、岩体失稳过程中所处的远离平衡态的情况与岩体失稳过程中的降维、减熵与有序性 ;讨论了岩石应力应变曲线与耗散结构形成的关系 ;以滑坡为例说明了耗散结构的形成过程 。
According to the three conditions of formation and sustaining of dissipative structure, the nonlinear characteristics, the state far from equilibrium, and dimension lowing, entropy reducing and ordering in the process of deformation and instability of rock mass, are studied from micro and macro aspects. The relationship between stress strain curve of rock and formation of dissipative structure is discussed. With an example of landslide, the forming process and method of bulding the dissipative structure model are explained.
