Abstract With the development of high speed railway，more and more attentions have been paid to the effect of vibrating load induced by high speed train on large cross-section tunnel. Based on the numerical simulation of vertical vibrating load induced by high speed train with excitation function，dynamic response of large cross-section tunnel under the vibrating load has been analyzed by elastoplastic finite element method；and the effects of different section forms，train speed and damping ratios on the dynamic response are also studied. Comparisons of dynamic responses between large cross-section tunnel and general one are performed.
