철도터널 콘크리트도상 궤도강성과 고체소음의 영향에 관한 연구

초록

The railway is recently becoming a representative for green-growth, and it also becomes an alternative for new growth with a lot of interests. Although it is possible that railway would be eco-friendly on aspect of efficiency. It also generates many damages of structure borne noise around railway because of speed up. That causes negative opinions for building railway except for subway adjacent area. Especially, subway that has essential roles for public transportation should not be placed near the roads, but also it needs to build structures for large-scale projects. It is necessary to have more studies how to improve existing railway to reduce structure borne noise. For reducing structure borne noise, it is approaching for repairs such as rail grinding, track maintenance works, wheel grinding until now. In this study, we predicted how to change structure borne noise according to changes of pad stiffness of concrete track in tunnel, and also predicted reduction with the Prediction Equation for Noise.
