광폭침목형 아스팔트콘크리트 궤도의 열차 주행 시 거동 분석

초록

Asphalt concrete track has been studied for a few years, which is a new concept railway track that combines the advantage between ballasted track and concrete track. Based on the results of the study, asphalt concrete track was inceptively constructed on the commercial line in Korea and field test is in progress. In this study, wheel load, lateral load, stress of rail bottom surface, vertical displacement of rail and wide sleeper were measured in wide sleeper type asphalt concrete track during train operation. The behavior of wide sleeper type asphalt concrete track was analyzed by the measured results. As a result of the analysis, it was confirmed that wide sleeper type asphalt concrete track was fitted to the requirements for track safety and stability.
