도시철도에서 콘크리트 궤도구조별 진동특성에 관한 연구

초록

This study performed the numerical analysis about the vibration characteristics generated at the urban transit adopted the concrete slab track according to track structures in which vibration is generated such as rail, concrete ballast and wall in tunnel. In addition, it measured the vibration characteristics which is same as track structure at urban railway generated on running train by speed. Also, as track structure is designed, it analyzed the method compared to the vibration characteristics though predicted numerical analysis to reduce vibration about a part of generation.
