岩石破碎的连续损伤力学模型

A MODEL OF CONTINUOUS DAMAGE MECHANICS FOR ROCK FRACTURE

本文简要介绍了损伤力学的基本内容及其研究进展,并在拉波德诺夫所定义的损伤因子的基础上,引入了一个描述岩石内部缺陷繁衍的参变量——完整度。从理论上建立了理想脆性岩石的损伤因子与完整度之间的本构关系,导出了理想脆性岩石破碎后的块度分布函数。

This paper introduced the basic contents and the research development of damaga mechani cs. On the basis of the damage factor defined by Rabotnov, it presented the intactness, a parameter which describes the propagation of the rock internal faults, established the constitutive relationship between the dumage factor and the intactness for the perfect brittle rock theoretically, and derived the particle distribution function of the perfect brittle rock.
