Abstract Recently a mesoscale model was developed that includes thermomechanically consistent constitutive equations with dissipation due to porous compaction, inelastic distortional deformation rate, and slipping on persistent dry joint surfaces. In this Part I of a two-part paper, enhancements of the mesoscale model are described which include: normal compliance with hysteresis, non-persistent joints with finite area, joint sets with angular deviation, and the weakening effect of fluid pressure in the joints. Examples study the influences of these effects on average strength. These computationally expensive simulations are used to inspire functional forms in a continuum model, described in Part II, which is needed for large scale simulations of real applications.

使用多个柔顺流体饱和节理组对岩体的动态响应进行建模 - 第一部分：中尺度模拟

摘要 最近开发了一个中尺度模型，其中包括热力学一致的本构方程，由于多孔压实、非弹性变形变形率和持续干燥的接缝表面上的滑动而导致耗散。在这篇由两部分组成的论文的第一部分中，描述了中尺度模型的改进，其中包括：正常顺应滞后、具有有限面积的非持久关节、具有角度偏差的关节组以及关节中流体压力的减弱作用. 实例研究了这些效应对平均强度的影响。这些计算成本高的模拟用于激发连续模型中的功能形式，如第二部分所述，这是实际应用的大规模模拟所需要的。
