Abstract：Research purposes:With the more and more high － speed railways being putting into service，the vibration influence of high － speed train on the surrounding environment is increasing gradually． In the coastal area，many high －speed railways are built on saturated soft clay foundation featured with the low shear wave velocity and high water content． The high － speed train could produce the big vibrations response to the saturated soft foundation． A slab track －saturated foundation coupled model was established to research the vibrations response to the saturated soil under the effect of the load of the high － speed train for the purposes of effectively overcoming the environment vibration induced by the high － speed train and proving the theoretical guidance to optimization of subgrade design of high － speed railway．
Research conclusions:The numerical results show using the multiple － aperture saturated medium to simulate the saturated soil foundation can more accurately analyze the vibration response induced by the high － speed train，enhancing the track stiffness can effectively control the rail displacement and increasing the thickness of the foundation bed in design can reduce the impact of the liquid phase medium in soil on the dynamic response to the soil．
