The observation elements include sample density, ambient temperature, confining pressure, compressive strength, peak strength, etc. The data collection time range is from April 20, 2018 to April 20, 2019. The low-temperature triaxial experimental device is used to measure the triaxial compressive strength of Mohe frozen soil and Dongying frozen soil under different buried depths, temperatures and confining pressures. It is used to study the variation law of mechanical parameters of frozen soil layer with temperature and confining pressure, and establish the prediction model of geotechnical mechanical parameters of frozen soil layer.
