The thermal consolidation response of saturated clay under different drainage conditions and temperature paths under hot and cold cyclic temperature loading was investigated using self-developed test equipment. For example, the temperature path is 25–75–25 °C, the number of cycles is 6 times, the peripheral pressure is 50, 100, 150 kPa, and the pore water in the specimen is always in the state of non-drainage in the whole test process except for the initial drainage and consolidation stage; the temperature path is 25–50–25 °C, and the pore water in the specimen is not discharged in the process of temperature increase/decrease and is discharged when the corresponding temperature is reached. Solidification. At the same time, the thermal consolidation characteristics of saturated clay under multi-stage heating/cooling cycle with temperature paths of 20–50–80–50–20 °C were also carried out.
