Abstract: In this paper, a mathematical mechanical mode! and the governing differential equations of the coupled problem ol temperature and seepage fields. with phase change, are lirst derived from the theory of heat transfer and the theory of seepage. Then the finite element formulae of this problem are obtained from (ialerkin's method. Finally, considering the seepage influence, an illustrative example of the temperature held in cold regions dam is provided. The example shows that the effect of seepage field on the temperature field of cold region dams is large. So the effect of this factor on Ihe dam temperature field should be taken into account in cold regions dam engineering design.
