Abstract
This paper summarizes the design of ballastless track structure of Changsha-Kunming dedicated passenger line, including CRTSⅠ double block ballastless track, CRTSII type slab track, transition section and the arrangement of rail expansion joint. With reference to the characteristics of Changsha-Kunming dedicated passenger line, the difficulties and key issues in the design of rail system are introduced to provide references for other similar projects. The form of ballastless track structure should be reasonably determined according to the types of substructure works and the track laying should be conducted in full sections. Railway lines in mountainous areas should adopt CRTSI double block ballastless track in order to reduce the quantity of rail temperature regulator. Large-span continuous beam sections may adopt CRTSIISlab track, and extra-long-span bridges should be provided with rail expansion joint. The ballastless track subgrade and transition section shall employ transitional measures.关键词
