열차의 주행 방향에 따른 교량-토공 접속부 변위 거동에 대한 수치해석적 비교 연구

Excessive vertical displacement occurring frequently in bridge abutment of railway has a significant impact on train service properties. In this study, comparative analysis on the different rail profiles caused by the different driving direction of the train vehicle was conducted. The vehicle was modeled via the multi-body dynamics technique. The entire track including the bridge, abutment, and embankment was modeled in the finite element method. Together with the driving direction of the vehicle, various velocity of train also was considered.
