사전제작 플로팅궤도의 구조성능에 관한 실험연구 = Experimental Study on Structural Performance of Prefabricated Precast Floating Track

국문 초록 (Abstract)

철도진동을 저감하기 위해서 선상, 선하, 지하 역사 구간을 대상으로 하여 철도운행의 지장 없이 기존역사 자갈궤도를 철거 후 제한시간내 설치하여 진동소음을 저감할 수 있는 방진장치가 부착된 사전제작형 플로팅 궤도(Prefabricated Precast Floating Track)가 최근 국내에서 개발되었다. 본 연구에서는 사전제작형 플로팅 궤도에 대한 구조적 성능을 검증하였다. 이를 위해 마찰형 방진장치가 부착된 프리캐스트 궤도 슬래브 패널 3개를 레일로 체결하여 정적 및 동적시험을 수행하고 1개 패널에 대해서는 피로시험을 수행하였다. 시험결과 3개 패널의 조립시험체의 레일과 패널은 요구성능을 만족하며 구조 안전성을 확보한 것으로 판단된다.

다국어 초록 (Multilingual Abstract)

To reduce railway vibration, prefabricated precast floating track along with an isolator for reducing vibration and noise was recently developed in Korea by removing existing gravel tracks within the required time without disturbing railway operations for station on the track, station below the track, and underground station sections. This study verifies the structural performance of the prefabricated precast floating track. To this end, three precast slab track panels with friction-type vibration isolators were fastened with rails for static and dynamic tests, and fatigue tests were conducted on one panel. The test results indicated that the rails and panels of the three-panel assembly test specimens satisfied the required performance. The floating track is considered to have sufficient structural safety.
