Abstract

Selecting a rational calculation model was the key for the research in dynamic response analysis on the ballast-less track-subgrade system of high-speed railway. According to the typical profile of ballast-less track subgrade, and supporting with finite element software ANSYS, 2D finite element models were constructed based on the subgrade with plate ballast-less track-multiplayer system. Computation parameters were determined by selecting a rational train load. Meantime, study the lateral distribution law of vertical displacement, stress, strain and vertical acceleration of subgrade cross-section directly beneath the train load at a time to analyze the dynamic response of subgrade to train load.
