摘要
岩体中通常含有大量断续状裂隙,它们对岩体结构的变形和稳定性有着不可忽视的影响。本文应用损伤力学原理,建立了这种岩体的弹塑性—损伤本构模型.室内试验和地下厂房实测验算说明,该本构模型是合理有效的.
Rockmasses generally contain a great mamy of intermittent fissures and joints. They affect the deformation and stability of the rockmass structure considerably、In this paper, an elastoplastic-damage constitutive model for rockmasses is proposed by the authors based on the principle of damage mechanics. The results of laboratory tests and the data of in-situ measurements of underground powerhouse excavations indicate that the model is reasonable and effective for the numerical analysis of rock engineering.
