Sensitivity analysis of the frozen soil nonlinear latent heat and its precise transformation method

SUMMARY Latent heat of soil water phase transition is an important parameter affecting the prediction of the temperature field in a frozen soil. With the nonlinear change of unfrozen water content in freezing soil, the latent heat appears nonlinearly in a frozen soil. To evaluate the influence of the estimation of phase quantity and phase change interval on the formation of the temperature field in a frozen soil, the thermal parameters at...
