在应力空间描述岩体损伤本构关系的一种模型

MODEL FOR A CONSTITUTIVE RELATION OF ROCK MASS DESCRIBED IN STRESS SPACE

在分析岩体细观和宏观损伤特征及其与岩体非弹性变形之间关系的基础上,运用损伤面来定义弹性—损伤准则,建立了在应力空间描述岩体损伤本构关系的一种模型,并对该模型在工程中的应用进行了讨论。

Based on the analyses of the micro-and macro-damage characteristics and their relation with the non-elastic deformation of rock mass, an elastic-damage criterion for rock mass is defined by using the damage surface. A model for a constitutive relation of rock mass dscribed in stress space is established and its application in engineering is discussed.
