파형강판 합성 U형 철도교의 소음성능에 대한 해석적 연구

초록

Railway bridges through the downtown region is an excellent bridge type noise reduction performance is required. According to this request, the bridge of the noise barrier installation is not required and low vibration is under development. This railway bridge is corrugated steel plates composite U-type. Because the bridge cross-section wraps a train and web contains the sound-absorbing system, noise is reduced. In this study, we analyzed the noise reduction performance of the corrugated steel plates composite U-type railway bridge using general noise analysis program.
