In this paper, the 3-D finite element model is used to systematically analyze the displacement field of artificial frozen soil thawing settlement. During the simulation process, the thermophysical parameters change with temperature, such as elastic modulus, density, specific heat and other parameters change with temperature. When calculating the temperature field of melting and settling, the temperature field on which the mechanical parameters are based is given point by point through the field variables. After changing with time, the temperature field changes with the points, and the mechanical parameters also change point by point. To ensure that the simulated melting and settling calculation process is more in line with the actual project. The calculation results of melting and sinking show that the whole displacement field presents nonlinear changes with time and space. The research results of this paper provide reference for the control measures of melting and settling.
