경부고속철도 2단계구간 궤도~구조물 상호작용 해석 및 적용

The construction of CWR is commonly known method and provides a lot of advantages. However, great caution should be paid to the maintenance of the CWR which is much influenced by the roadbed condition, the change of weather and temperature in order to secure safe train operation. For the construction of the CWR on the bridge, the safety of the CWR should be secured by evaluating the safety and by applying appropriate measures and track materials to the CWR after reviewing the interaction between bridge and track. As the Kyoung-bu 2nd stage HSR project cited in this article would be constructed with slab track, the safety of the CWR on the bridge was evaluated on the basis of UIC code which is internationally used, and DS 804 which is German standard for slab track. In this article, the analysis of the interaction between track and bridge commonly used in Korea was compared with the analysis recommended by UIC 774-3R in order to review the applicability of more reasonable value in the design of structures.
