关于地质材料内部构造层次的若干模型

On some models of internal structural hierarchy of geomaterials

材料的内部结构对于材料的宏观行为有显著的影响。同时外部作用也会对于材料的内部结构产生影响,在岩石及岩体的破坏过程中也会形成新的结构,并进而对于材料的宏观行为产生影响。因此在研究地质材料的变形与破坏时必须考虑其内部构造。本文对这方面的某些模型进行了回顾,并对需要研究的问题作一些的展望。

Internal structure of materials has remarkable effect on the macroscopic behavior of the materials. At the same time external actions affect the internal structure of the materials and cause the formation of new structures, and in turn new structures influence the macroscopic behavior of the materials. Hence the internal structure of the materials must be considered in the study of deformation and fracture of the materials. In this paper some models of structural hierarchy of geomaterials are reviewed and the remaining issues in need of further research are indicated.
