英文摘要	For the railway engineering and important lifeline engineering, seismic performance of bridge structure is considered by researchers and engineers. Isolation technology is widely applied in order to prevent the damage of bridge under earthquake effect. Serial seismic isolation system (SSIS), including isolation bearing such as laminated rubber bearings and sliders, has become an important supported component of isolated bridge. Taking the serial seismic isolation system as the investigated subject, several models of serial isolation system under horizontal and vertical load are analyzed with the finite element software, considering different parameters. The results indicate that these parameters have great influence on the deformation of serial seismic isolation system. The height of RC column influences the displacement of top surface of SSIS greatly, the higher the height of column, the greater the displacement of SSIS. And the displacement of top surface of SSIS is affected obviously by vertical load, which increases with the vertical load. The vertical load bearing capacity of SSIS reduces when the horizontal displacement increases.
