Countries' long-term railway network plan \200 km and more. Although the rapid development of China's high-speed railway, the the Ballastless theory research started earlier, but has not yet formed system Ballastless track design theory, design methods, and mature experience in construction, which must accelerate the Ballastless research speed, Ballastless Track calculated structure calculated parameters, evaluation methods, systematic and comprehensive study to form a unified Ballastless Track design theory and methodology, in order to facilitate a better guidance of China's high-speed rail Ballastless orbit construction. In this paper, the Wuhan-Guangzhou Passenger Line Rheda2000 double block ballastless track as the research object, the application of the finite element analysis software ANSYS analysis of double-block ballastless track concrete road bed board on the bridge in the track loads and temperature loads Ballastless stress response and displacement response. The main work of this paper include the following aspects: (1) Rheda2000 type double block the Ballastless Track Road the bedplate focus construction technical points summarize. (2) Select the correct calculation unit, establish a reasonable calculation model proposed under different temperature load combination Road Chuangban load conditions. Abutment, the middle layer and sleeper cells SOLID45 simulation the road bed board SOLID65 unit simulation, rail with BEAM188 unit simulation, fasteners with COMBINE39 unit analog. Respectively, the overall structure of the finite element model, abutment model, the middle layer model, said bed board and sleeper model, rails and fasteners model. (3) calculated by the numerical simulation method bridges on the system the double block ballastless Rail Road Chuangban track load and temperature loads deformation, displacement response and stress response, including the summer load winter load spring and autumn loaded three different temperature loads. (4) the actual project temperature stress is the main form of concrete failure, it seems from the different seasons temperature response under load, the maximum tensile stress of the road bed board summer load and winter load to load much larger than the spring / autumn, showing the temperature load pull Stress the main reason for the increase. (5) in different seasons temperature loads, the maximum displacement and stress of the channel bed board in accordance with the design requirements, and stress showed good symmetry. Loading of the summer, the top of the system presents the trend of the expansion, presents the trend of \The trend presents \Under load in the spring / autumn, in the absence of the temperature gradient, the system does not have the \
