西部寒旱地区干燥、寒冷、温差、强紫外线和大风等气候特征形成了干湿冻融循环、冷热交替等典型的自然条件,对西部寒旱地区的恶劣气候环境下的岩石冻融损伤机制进行分析,详细阐述了岩石的冻融损伤过程,然后分析了冻融循环、冻融温度、化学环境和应力状态等外部影响因素对岩石冻融损伤的影响。
The climate characteristics of dry and cold winter, cold, temperature difference, strong ultraviolet and strong wind in western cold arid regions form typical natural conditions such as freeze-thaw cycle, alternating hot and cold conditions, and freeze-thaw damage mechanisms under severe climatic conditions in the western frigid regions Analyzed the freeze-thaw damage process of rock in detail, and then analyzed the influence of external factors such as freeze-thaw cycle, freeze-thaw temperature, chemical environment and stress state on rock freeze-thaw damage.
