论文摘要
本文介绍了一个模型，其中热 - 冰科机电过程与先前存在的裂缝的变形模型耦合。该模型是在离散折叠式摩托框架中配制的，在离散裂纹 - 摩托框架中，岩石矩阵和断裂被视为单个子域，它们之间的相互作用发生在矩阵裂缝接口上。在模拟工具箱porepy中实施的有限体积离散化被提出并应用于模拟中，展示了不同机制对由接触力学控制的裂缝变形及其不同的时间表的影响。
This paper presents a model where thermo-hydro-mechanical processes are coupled to a deformation model for preexisting fractures. The model is formulated within a discrete-fracture-matrix framework where the rock matrix and the fractures are considered as individual subdomains, and interaction between them takes place on the matrix-fracture interfaces. A finite volume discretisation implemented in the simulation toolbox PorePy is presented and applied in a simulation showcasing the effects of the different mechanisms on fracture deformation governed by contact mechanics, as well as their different timescales.
