Abstract: Based on the substructural analysis of soil-structural interaction, sleeper-subgrade-site is treated as a subsystem and separated from the coupled system of train-rail-subgrade-site, and the input of dynamic load is considered as a boundary condition. As a trial, the measured time history of the vertical velocity of the sleeper induced by high-speed train in-situ experiments is used as an input of dynamic load. By means of this method and ABAQUS software, the parametric studies of dynamic response of subgrade-site system induced by high-speed train are completed by making non-linear numerical analyses and considering train running condition on up-link and down-link under the different combination with train speed 265 km/h and 300 km/h. Some preliminary regularity is presented.

Key words: high-speed train, site vibration, dynamic response, ABAQUS software
