Design Scheme for Mountain Rail Transit Track Structure
The mountain track has strong climbing ability,fast climbing speed,and low construction cost.Based on a systematic summary of the current research status of toothed rail transit at home and abroad,this article conducted a systematic design study on the track structure scheme of toothed rail railways,proposed three types of track structure forms suitable for mountain tracks,which are structural schemes for ballastless track,polyurethane cured ballast bed,and ballasted track,provided its main technical parameters and analyzed the advantages and disadvantages of three solutions from the perspectives of operating conditions and economy.The results indicate that the stability of ballastless track structure is the best,followed by polyurethane cured ballast bed structure.The ballasted track structure has the best economic efficiency.It is recommended to adopt a ballasted track structure scheme for general section and to adopt the ballastless track structure scheme for sections with larger slopes.
