Generally, ray theory can't take into consideration the diffraction due to the discontinuities in the geometrical solution field. If it can be able to estimate the effect of diffracted waves by ray theory, ray theory is very useful to calculate surface response for a dipping layer. In this paper, an approximate solution which taking the effect of diffracted waves into account is presented for the surface ground motion of a dipping layer. It is based on the ray theory. Time dmain results are presented for different property constants. Comparison of results with a more rigorous solution (boundary element method) shows very good agreement. This method is suited to study for the response analysis of a dipping layer in time domain due to its low cost.
