A feasibility study on adoption of slab track for the new high speed rail way line between Daegu and Pusan

대구-부산간 고속철도 신설선에 대한 슬래브 궤도구조의 도입 타당성에 관한 연구

This Study is about adoption of slab track on the new high speed railway line between Daegu and Busan. While ballast track currently used is easy to construct with low investment, the error margin of rail track occurs in the track due to the repetition load of the train. Therefore, repairs should be carried out all the time to put the railway track at the repair level or less. In addition, noise caused by such repairs has become a new social problem at night. Construction costs for slab track are about 1.3-1.5 times higher than those for ballast track. However, slab track will save labor costs by solving various problems of ballast track. In this regard, it is feasible to adopt slab track on the new high speed railway line between Daegu and Busan.
