The development of special finite difference method for nonlinear dynamic response analysis of semi-infinite foundation soil is presented here. Semi-infinite domain is mapped into finite domain using special mapping. For the region of engineering interest, mapping is isometric, and for far field, shrink mapping which transforms infinite interval into finite interval is adopted. Using simple linear and nonlinear constitutive models, the responses of semi-infinite foundation soil are computed by the proposed method with small mesh model and with large mesh model. Surface loadings and incident earthquake waves are applied to the models. For linear model, good agreements are obtained between computed and theoretical results. For linear and nonlinear models, the results of small and large mesh models agree well with each other, demonstrating the effectiveness of the proposed method.
