Recently, for the long-period ground motions by the Tokai earthquake, the Tonankai earthquake, et al., the safety of Tokaido-Shinkansen becomes a problem. In this paper, using the analytical model of high-speed moving railway vehicles proposed by Shintani, et al., its dynamic behavior is studied by use of the artificial long-period ground motions in lateral and vertical directions simultaneously. From the analytical results, some relationships between the lateral ground motion and collision of some stoppers on the possibility of rollover of the vehicle are shown. Also, it is clear that the possibility of rollover of the vehicle is large for the long-period ground motions used in this study.

In this paper, Using the analytical model of high-speed moving railway vehicles proposed by Shintani, et al., its dynamic behavior is studied by use of the artificial long-period ground motions and actual ground motion in lateral and vertical directions simultaneously. From the analytical results, some correlation effects between the lateral ground motion and vertical ground motion on the possibility of rollover of the vehicle are shown. Also, it is clear that the possibility of rollover of the vehicle is large for the long-period ground motions used in this study.
