ABSTRACT

Previous researches have achieved certain results. But from the perspective of water filled fissure, the study of frost heaving force evolution with the temperature decreasing is rarely reported. We study the fractured rock hard internal temperature field and heaving loads development process according to the theory of heat transfer, phase transitions, elastic-plastic mechanics. We propose corresponding analytical expressions, and use the multi-field coupling program Comsol Multiphysics to simulate. The study provides a good reference to the temperature and stress field evolution analysis in fractured rock mass under low temperature.
