No Ballasted Track General-purpose Reference Map Series Division Plan Study

This paper firstly carries on the induction and summary of all kinds of ballastless track structure pattern, discusses requests for ballastless track under different line standards, at the same time, mainly analyzes and studies the train load and thermal load influences on ballastless track structure and preliminary make out the division scheme of general reference diagram series for ballastless track in our country.Through analysis and the discussion of this article, general reference diagram for ballastless track can be divided in the first level according to the structure pattern, that is the CRTS I slab track general reference diagram, the CRTS II slab track general reference diagram, the CRTS I bi-block ballastless track general reference diagram, the CRTS II the bi-block ballastless track general reference diagram, general reference diagram for slab track with long sleepers embeding concrete and the general reference diagram for track with elastic bearing block.Division of second level can be carried on according to the operation condition, that is the 300-350km/h passenager dedicated line, the 200-250km/h passenager dedicated line (taking freight transport into account), the 200-250km/h passenager dedicated line (inter-city railway) and below 200km/h mixed passenger and freight railway .Finally, based on the first level and secong level, ballastless track can be divided into the roadbed, the bridge, the tunnel and the rail switch area according to the the sub rail foundation structure pattern, severely cold, cold and the warm area according to the temperature region, and shoulder-block fastener and non shoulder-block fastener according to fastener pattern.
