In this paper, the coupling method of spline finite element and semi-analytical in-finite element is extended to the solution for the seismic response of the underground. Thecoupling method not only has the advantage of reducing the dimensions and the number ofthe degree of freedom, but also can avoid the artificial boundary and has the capability ofconsidering the complex layer soil. The method presented herein provides a valid way to studythe mechanism of soil-underground structure interaction.
