A Study on noise characteristics of concrete slab tracks

콘크리트 슬래브궤도의 소음특성에 관한 연구

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 grasp noise characteristics on slab tracks we measured noise on high speed rail slab track in addition Saemaul and Moogungwha and the results have done comparative analysis.
