中文摘要：
考虑损伤的各向异性定义了张量型损伤变量,综合考虑温度-渗流-应力-损伤耦合对岩体的影响,求解应力平衡方程推导出损伤区注采生产诱导应力计算模型。根据热力学原理,求解岩石的热弹性物理方程得到弹性区注采生产诱导应力计算模型。模型中张量损伤变量从孔隙度变化的微细观角度描述了损伤特性,文中所揭示的规律为注采生产诱导应力计算找到了新的理论和方法,对生产有积极的指导意义。
英文摘要：
A new tensor damage variable is defined based on the anisotropy of damage.Allow for the combined action of temperature,seepage,stress and damage to rock mass,the computational model of injection induced stress in damage zone is deduced by solving stress equilibrium equation.The computational model of injection induced stress in elastic zone is deduced by solving thermoelastic physical equation.The tensor damage variable describes the damage behavior from the standpoint of microcosmic.The law in the paper has provided a theory and method to compute induced stress of injection,which is important to production.
