A Study on noise characteristics by site types of concrete slab tracks

콘크리트 궤도의 구간별 소음특성에 관한 고찰

The construction of concrete slab track system is increased because the system has advantages which are maintenance free and so on, the other side, the system has weak points such as increase of the cost of the early stage construction. Recently, railway environment is issued including noise. Therefore, measures which are to mitigate noise on slab tracks were introduced, however, it is found that efficiency of noise reduction is low because noise problem is still issued. In this study, to study noise characteristics on concrete tracks we measured noise by site types. Finally the results have done comparative analysis.
