A solution for the displacement in a multilayered medium subjected to dynamic and static loading in its interior is presented. It is shown that the displacement can be calculated by two kinds of transfer matrix which are 'layer field matrix' and 'layer boundary matrix'. The influence of the external loading is included in the 'layer boundary matrix'. The size of these matrices are 5×5 for the P- and SV-waves and 3×3 for the SH-waves. In order to verify the solution, comparisons with existing solutions which are the Lamb's, Mindlin's and Matsoka-Yahata's solution were performed for some particular cases. As a result it is shown that the solution in this paper agrees with these existing solutions.
