摘要：A hybrid procedure combining wave functions expansion and finite element method is developed to study the dynamic response of tunnel or cavity of any shape buried in halfspace or in fullspace under incident seismic wave. The near field containing inhomogeneities is modelled by conventional finite element method and the homogeneous unbounded far field is represented by a set of wave functions expansion. The traction-free boundary condition of the surface extending to infinity is enforced on pointwise basis for halfspace problems. Various kind of numerical examples are given, and satisfactory agreements are obtained with the analytical results available.
