摘要
In this paper, the governing differential equations of the coupled problem of temperature and seepage fields with phase change are first derived from the theory of heat transfer and the theory of seepage. Then the finite element formulae of this problem are obtained from Galerkin's method. Finally, an illustrative example of the temperature field in a cold regions tunnel with large porosity, considering the seepage influence, is provided. The example shows that the influence of seepage on the frozen depth of the tunnel with large porosity is very large and thus, the effect of the seepage factor should be taken into account in the cold regions engineering design.
