Abstract：
With the development of rail transit construction in recent years, the study of train vibration and vibra? tion isolation has produced a general concern in engineering. As the 2.5D FEM is efficient at analyzing complex dynamic problems, this paper sums up thoughts about the 2.5D FEM analysis application and the research status of train vibrations and vibration-isolation issues from the two aspects of elastic subsoil and saturated subsoil based on domestic and overseas investigations. Previous research has mostly focused on the elastic subsoil and railway trains;a few studies have focused on the saturated subsoil, subway trains and calculation method optimization, but only considered the effect of a single train on surroundings and buildings instead of the vibration response between adjacent trains. In light of the characteristics of dynamic problems concerning train operation, this paper discusses potential directions for research of and prospects for train vibrations and vibration isolation analysis by 2.5D FEM.
