Abstract Numerical simulation analysis of channel frost heaving dependeds on measured temperature and therefore can not directly forecast channel frost heaving and design. To avoid the default, considering effect of sunlight on frost heaving deformation and frost heaving pressure, based on frost heaving mechanics， frost heaving physics and theory of heat radiation, dynamic numerical simulation of channel daily frost heaving process was conducted by using ANSYS to load temperature. Distributions of channel temperature, stress and deformation fields were obtained. By comparison, the frost heaving rule with heat radiation consideration is consistent with that caused by measured sinusoidal temperature change, the soil temperature is higher than that gotten from sinusoidal temperature change method, especially at channel shady position, frost heaving deformation and frost heaving pressure are lower than that calculated by sinusoidal temperature change method.
