岩石损伤理论研究进展

介绍了近年来岩石损伤理论若干进展,主要内容包括:岩石损伤理论的基本思想及其研究方法、岩石损伤的分类、损伤变量的定义与选取、岩石损伤本构模型的建立及其参数对岩石损伤行为的影响、不同荷载下岩石裂纹演化规律的研究、岩石损伤机理的探讨,以及对岩石损伤的一些认识。以上研究表明:首先,采用损伤力学对岩石损伤进行研究是一种行之有效的方法。其次,损伤模型的建立是岩石损伤的核心内容。通过室内试验研究岩石在不同荷载下的损伤演化规律,有助于揭示岩石损伤机理。最后提出下一步研究的重点是考虑多因素岩石耦合损伤。

Progress of Theoretical Research of Rock Damage

Some progresses about rock damage theory in resent years,including the basic ideas and research methods of rock damage theory,the classification of rock damage,the definition and selective of damage variable,the establishment of rock damage constitutive model,and also it's parameter that impact on rock damage conduct,the law of rock evolution researches under different loads,the investigations of rock damage mechanism,the acquaintances of rock damage are introduced in this article.Above studies show that: F...
