Experimental Analysis of Vibration Transfer Characteristics of an Elevated Railroad Station
Journal of The Korean Society of Disaster Information, 2015 선하역사 내부에 발생하는 소음을 저감하기 위해서는 진동의 감소가 필요하며, 보다 효 과적인 진동 저감 대책 수립을 위해서는 궤도-접속교량-구조물의 상호작용 특성을 감안 하여 열차 운행으로 발생하는 진동이 전달되는 경로 및 특성에 대한 명확한 이해가 필 요하다. 이 논문에서는 국내 선하역사 현황을 구조적으로 분류하고 대표 선하역사에 대 한 진동 측정을 통하여 역사에 발생하는 진동의 전달 특성을 분석하였다. 주파수응답을 통한 분석 결과 궤도의 진동이 역사로 전달되면서 고주파 성분이 큰 감소를 나타냈으 며, 일부 역사에서 저주파 대역 내 증폭 구간이 발견되었다. 플로팅궤도가 적용되거나 TPS 구조의 역사는 궤도로부터 전달되는 진동이
