[Abstract]:The new railway passage in central and southern Shanxi is the first heavy-haul railway with a designed axle load of 30 tons in China. The composition and technical characteristics of ballastless track structure of double block type, long pillow embedded type and elastic support block type on mixed passenger and cargo transportation lines in China are analyzed. The ballastless track with elastic support block is selected as the structure of ballastless track in the heavy haul railway tunnel. The main points of structure design of elastic bearing block ballastless track are expounded, the design scheme of the connection between ballastless track and tunnel bottom is given, the precast quality of elastic support block and the key technology of quality control in key working procedure of track construction are analyzed. The optimization suggestion of tunnel drainage system design is put forward. This paper can provide reference for the design and construction of ballastless track structure in heavy haul tunnel.
