摘要：

An integral equation for the influence of spatial variability on seismic soil-structure interaction is proposed. The fundamental solution for a reference medium is required. It is obtained by means of substructuring techniques and boundary integral equations using the Green tensors for homogeneous or horizontally stratified reference media. The effects of a non-stationary modulated random incident field are addressed in terms of the instantaneous power spectral density of the structural response. The effects of soil moduli perturbations are also investigated and a first order approach for the structural response is given in case of weak fluctuations.
