Abstract：The problem of semi-infinite space with layered medium in the finite element model and corresponding Rayleigh wave input was solved by using equivalent viscous-spring artificial boundary elements. Based on the secondary development of the interface program, an example of two-dimensional finite element model of even and layered medium had been developed. The results indicated that finite element method had excellent estimation precision compared with theory. The dynamic response of pile-soil-bridge structure dynamic interaction under Rayleigh waves was analyzed. A typical rigid frame bridge had been included in this case study. The influence of different site conditions, changes in the location of the soft interlayer, different Rayleigh wave input and pile length on Rayleigh wave propagation and seismic response are considered. The influencing factors of the rigid frame bridge structure are also discussed.
