Abstract:
The temperature field of artificial frozen soil is a transient temperature field which relates to both space and time involving phase change. Regarding exponent-integral function as an analytical way of transient temperature field of artificial frozen soil, the feasibility of the analytical solution and its logarithmic distribution law on both space and time are confirmed by the approximate progressional expression of exponent-integral function and the engineering application. The theoretical function expression between the expanding depth and velocity of frozen soil wall and freezing time is acquired according to freezing procedure of phase change. Therefore, a new way of analyzing the distribution of temperature, the expanding depth, strength, as well as the freezing time of artificial frozen soil is provided for freezing engineering.
