초록

철도기술의 발달에 따라 열차의 주행속도는 점차 증가하였으며 최근에 들어 400 km/h 이상의 초고속열차가 등장하기에 이르렀다. 최근 우리나라에서도 열차의 주행속도를 300 km/h에서 350 km/h 이상으로 증가시키려고 했으나 주행 시 소음 및 진동의 문제가 발생할 우려가 있어서 현실화되지 못하고 있다. 그러나 고속열차의 주행속도가 증가함에 따라 소음 진동이 증가되는 피해가 우려되며 그 중에서도 철도 역사는 고속열차의 정차 및 통과시에 열차와 가장 근거리에 위치한 건축물로써 열차소음에 의한 사용자의 피해가 가장 크게 발생한다. 소음의 피해는 고속철도 역사의 건축방식에 따라 다를 것으로 예상되며 본 연구에서는 지하역과 선하역 2종류, 지상역, 선상역 등 총 5가지의 역사형식의 고속철도 역사를 대상으로 소음분석을 실시하였다. 본 논문에서는 고속열차의 속도 증가에 따른 역사의 실내 소음 을 예측하고 실내 허용 소음기준(Noise Criteria, NC)과 비교 분석하여 적정성을 평가하였다. 또한 차음성능 예측 공식 및 컴퓨터 프로그램을 활용하여 건축 부위별 마감재의 차음성능을 계산하였다. 최종적으로 마감재 변경을 통해 역사시설의 소음환경이 적정 실내허용소음을 만족할 수 있도록 개선하는 일련의 과정을 도출하고자 한다.

The speed of train has rapidly been increased in accordance with the developed railway technology. Nowadays, high-speed trains were introduced which has the speed faster than 400 km/h. In Korea, a lots of efforts were undertaken to increase the speed of train faster than 350 km/h, however noise and vibration are still the main problems to solve for realization of the high-speed train. In the case of operation speed faster than 350 km/h, it can be easily presumed that the noise and vibration damages could be increased in the train stations which are close to the passing railway tracks. Thus, the noise in the five different types of high-speed train stations were analyzed including stations built on the ground, underground, under rail, and two types on rail. The present paper predicts noises inside the stations depending on the speed of the passing trains and analyze the noise comparing with noise criteria (NC). Sound insulation performance of each part of buildings was calculated using the transmission noise formula and computer modeling, Finally, a series of processes were introduced to satisfy the aural environment with the optimum interior noise criteria by changing interior finishing materials.
