Abstract Part I of this two-part paper describes enhancements of a mesoscale model to include: many non-persistent fluid saturated joints with finite area, normal compliance with hysteresis and the weakening effects of angular deviation in the joint sets and of fluid pressure in the joints. The objective of this Part II is to use the results of the mesoscale model as simulated data to inspire functional forms in a continuum model for rock masses with multiple compliant fluid saturated joint sets which include these enhancements. Also, an algorithm is proposed for reducing the number of joint sets being modeled. Examples are presented which show that the continuum model can predict similar anisotropic response to that observed in mesoscale simulations. In contrast with the mesoscale model, the continuum model can be used for large scale simulations of real applications, smoothly transitioning from coupled inelastic thermomechanical response near an explosive source to orthotropic elastic response far from the source.

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 - 第二部分：连续体建模

摘要 这篇由两部分组成的论文的第一部分描述了中尺度模型的增强功能，包括：许多具有有限面积的非持久流体饱和关节、对滞后的法向顺应性以及关节组角度偏差和流体压力的弱化影响。关节。本第二部分的目的是将中尺度模型的结果用作模拟数据，以激发具有多个柔顺流体饱和节理集的岩体的连续模型中的函数形式，其中包括这些增强功能。此外，还提出了一种算法来减少正在建模的关节集的数量。给出的示例表明连续模型可以预测与在中尺度模拟中观察到的类似的各向异性响应。与中尺度模型相比，
