초록

선하역사는 역사 건물의 상부에 위치한 노반구조물을 통하여 열차 운행으로 인한 진동이 직접 역사 구조물로 전달되므로 소음 진동에 취약한 구조이다. 선하역사 내부의 소음은 주로 구조물의 진동으로 인하여 발생하는 고체소음이므로 보다 효율적인 진동 저감 대책의 수립을 위해서는 역사의 구조 형식, 부재 및 재료 등의 구성 요소에 따른 구조적 거동 및 감쇠 특성의 파악이 중요하다. 이 논문에서는 선하역사와 인접 교량과의 접속부의 역학적 특성에 따른 진동 특성 변화에 대한 검토 결과를 제시하였다. 해석 대상 역사는 대천역이며, ABAQUS로 유한요소해석을 수행하였다. 접속부 특성은 접속 교량이 있는 경우와 없는 경우, 그리고 있는 경우 라멘식과 받침형식으로 구분하여 검토를 수행하였다.

Since the vibration induced by a train is transferred directly to a station via a roadbed structure, the elevated station is particularly vulnerable to noise and vibration. To establish more appropriate measures to reduce vibration, the structural behavior and damping characteristics depending on the structural type and the composition of a elevated station should be identified, because the noise inside the station is mainly structure borne noise by the vibration of a station structure. In this paper, the vibration characteristic changes depending on mechanical connection types between an elevated station and a connected bridge are analyzed. The finite element model for Daecheon Station is constructed for the purpose of this study, and the analysis is performed using ABAQUS. The analyses are conducted for with and without bridge connections, and for the bridge connections, ramen and bearing types are considered in the analysis.
