Abstract
In this paper, based on the experimental parameters of polar permafrost formation, the mathematical module, solid mechanics module, and Darcy?s law module of COMSOL Multiphysics software are used to realize the coupled solution of PDE of temperature field, moisture field, and stress field considering the ice-water phase transition and moisture convection, and the relationship between the permafrost moisture convection and temperature change is analyzed by using the heat-flow-solid-moisture mutual coupling, which reveals that the law of action of low temperature intrusion into rock formation by polar drilling.
