摘要
在对一些经典的岩石损伤模型评述的基础上 ,指出它们存在着简化和近似的局限 ,并提出一种新的指数—抛物线损伤模型 ,它以临界损伤点为界 ,将损伤分成虚拟损伤和实际损伤两个过程 ,前者损伤变量服从指数型分布 。
Based on the evaluation of a few classical rock damage models,the paper pointed out their existing limitations of simplification and approximation and put forward a new Index-Parabola Damage Model,which is divided into fictitious damage and real damage bordered by the critical damage point.The damage variable follows index distribution in the former stage and parabola distribution in the latter one.It was used to simulate the damage procedure of marble under uniaxial loading.The results prove to be good by experiments.It reflects the nonlinear characteristic of rock deformation very well.
