Abstract

Based on the freeze-thaw(F-T) and uniaxial compression test, the article focuses on the damage evolution model of rock masses under coupling action of F-T and load. In this study, a prediction model of rock under uniaxial compressive tests and F-T action was proposed in accordance with elastic-plastic theory and fatigue damage mechanics. This model was validated by the previous experiments including four kinds of rock samples. The results show that the damage evolution model is more reliable for all the chosen rocks with different geometric parameters of fissures, These conclusions lay the theoretical foundation for further development of damage evolution model of fractured rock under F-T cycles for natural building materials and engineering construction in cold regions.
