摘要

Multi-field coupling is one of the important forward subjects in geotechnical engineering and the coupled analysis of thermo-hydro-mechanical field is one of the most important parts of the multi-field coupling.Based on the thermo-hydro-mechanical coupling model for frozen soil and the 3G2012 software developed by the coupling theory, the temperature field, deformation field and stress field are investigated in this paper and the numerical results has been compared with the measured data which are well agreed with each other.The results indicated that the deformation of roadbed can be divided into two parts: frost heaving and thaw-settlement.Frost heaving period is from middle of November to next April and thaw-settlement period is from the beginning of May to the next beginning of November.This research result has directive significance to the similar project.
