Abstract:从岩石的细观非均匀性特点出发,应用损伤力学、热力学和渗流力学理论,建立了岩体热(温度)-水(渗流)-岩(应力)-损伤耦合数值模型(THMD
   model),把岩石(体)THM耦合问题的研究从应力状态分析深入到损伤、破坏过程分析之中。探讨了THM耦合作用下岩石材料的细观结构损伤及其诱发的
   材料力学性能演化机制,并运用所提出方法计算温度-渗流-应力耦合作用下井筒近场围岩的稳定性,模拟得到的岩体破坏过程、应力分布、AE特性及渗流特性变
   化与现场标定结果有着一致的规律性,初步证明了该数值模型的合理性和有效性。THMD模型以简单的数值模型表征了岩石(体)中热、水、岩及损伤之间复杂的
   作用关系,为从细观损伤演化揭示宏观岩体温度-渗流-应力耦合破坏机制提供了一种新的数值分析方法。
