The observed factors included sample density, ambient temperature, confining pressure, compressive strength, peak strength, etc. The time range for data resource collection was from April 20, 2018 to April 20, 2019. A low-temperature triaxial experimental device was used to measure the triaxial compressive strength of Mohe permafrost and Dongying permafrost at different burial depths, temperatures, and confining pressures. Used to study the variation of mechanical parameters of frozen soil layer with temperature and confining pressure, and establish a prediction model for geotechnical engineering mechanical parameters of frozen soil layer.
