In line non-ballasted track Suiyu comprehensive test section early construction, China's non-ballasted track While there has been a lot of research results, but for non-ballasted track passenger line only on bridges and tunnels in other tests carried out test shop work sites, yet laying carried into sections, especially the roadbed and non-ballasted track turnout area studies essentially blank. In this context, this paper carried out research to base line segment Suiyu laying slab track, two-block area non-ballasted track and turnout sleepers laid buried non-ballasted track for the study, the three non-ballasted track structure the design and construction of its research. First, the test section on the slab track roadbed structure design, analysis of the fasteners, track plate, CA mortar adjustment layer, base, composed of convex block Taiwan structural design requirements and design principles; studied slab track and ballasted track transition section design methods; established a slab track finite element model for concrete slab track roadbed Lot supporting layer settings issues were discussed. Lots for slab track roadbed construction technology research, analysis of the construction process, construction content, construction methods, construction principles and so on. Secondly, the test section Subgrade double block non-ballasted track structure design, analysis of the bi-block sleepers, road bed board, the base (support layer) composed of structural design requirements and design principles; studied the curve section and high bi-block track with ballasted track transition section design methods; establish a bi-block track roadbed Lot overall finite element model of the elastic modulus of concrete supporting layer on the track structure of the force. Lots double block on the roadbed non-ballasted track construction technology research, analysis of the construction process, construction content, construction methods, construction principles and so on. In addition, for the test section Cai Station on the 12th and the 18th non-ballasted track bed turnout, turnout area for non-ballasted track sleepers embedded structure design, mainly for road beds, concrete foundation, the transition section and switch machines installed base of research. Assessment of non-ballasted track laying works turnout District line conditions, laying turnouts in situ assembly method, non-ballasted track turnout District Road mattress base and concrete construction technology, non-ballasted turnout welding locking technology research. Finally, in the test section for non-ballasted track structure and fastenings dynamic performance test and turnout areas and non-ballasted track structure with movable track turnout dynamic performance tests. China with independent intellectual property rights for non-ballasted track design, construction technology has been verified.
