Ballastless Track Construction Technology Of Wuhan-Guangzhou Passenger Dedicated Line

in order to meet the requirements such as smoothness, quickness and comfort of high-speed railway, railway lines must have the good performance in continuous structure, stability, less maintenance and durability. Because the ballastless track is superior to the traditional ballast track in the form of the above performances, ballastless track is widely applied in the high-speed railway construction abroad. Wuhan-Guangzhou Passenger Dedicated Line has appied Rheda2000 Ballastless track Construction Technology and main construction equipments from Germany. According to the construction experience in the Ballastless track of Section III of Wuhan-Guangzhou Passenger Dedicated Line, the construction technology and construction organization have been designed in the thesis. Especially, the key construction technology and quality control technology, such as construction of supporting bed of Rheda2000 Ballastless track, prefabrication of bi-block sleeper, cast-in-place of road bed slab and laying of long rail, have been deeply studied. Ballastless track Construction of Section III of Wuhan-Guangzhou Passenger Dedicated Line has been finished, which conform to the requirements of engineering acceptance, and Wuhan-Guangzhou Passenger Dedicated Line will be fully operational by the end of October, 2009. The research results of the thesis will have the practical application and knowledge values for the development of Ballastless track Construction Technology in the Passenger Dedicated Line in China.
