岩体损伤力学理论进展

回顾了对损伤及岩体损伤理论的发展历史，并简要介绍了岩体损伤力学的主要内容，任务和研究它的若干假设，详细讨论了什么是损伤的表征，什么样的变量可作为损伤变量及如何用直接的或间接的，力学的或物理学的方法来测量它们，研究表明，岩体的损伤是在初始损伤的基础上累进性发展的，是不可逆的，研究材料的损伤演化时，可引进一些能反映材料内部结构变化的内变量构成损伤演变方程，损伤演变过程的研究也必是今后研究的热门。

Development of the Rock''''s Damage Theory

This paper retrospects to the development of the rock's damage theory and introduces the main content, task and several hypotheses briefly. It also discusses the display of damage, the damage parameters and how to measure them with direct or indirect methods of mechanics or physics. The research indicates that the damage of rock develops accumulatively on the basis of its initial damage and is irreversible. During the research of the evolution process of damage, some new parameters which. can indicate changes of rock's inner construction are introduced to form equations of damage evolution. In addition, research about process of damage evolution is a hot point in future.
