Abstract: The infrastructures in the cold and high-altitude regions play an important role in the social development, which are also the life and supply lines that connecting the economic development of the inland and remote areas. In the future potential wars, the safe protection of the frozen rock protection media under different environments should be considered. The study of the frozen rock engineering in cold regions is of the great significance to the engineering construction and the protection of important facilities in high altitude areas on the plateau. In this paper, the research results on the static and dynamic mechanical properties of the frozen rock at home and abroad in recent decades are summarized, mainly from the aspects of strength characteristics and deformation characteristics. The mechanism of the influence of the static and dynamic mechanical properties on the porosity ice is emphatically analyzed, and the discussion and prospect of the failure theory of frozen rock under the coupling effect are put forward, so as to provide scientific support for the engineering construction and protection in cold regions.
