Abstract
In view of the structural characteristics of CRTS Ⅰ double block ballastless track,a design scheme with reasonable techniques and economic efficiency is put forward.The structural stress of the traditional CRTS Ⅰ double block ballastless track and the optimized one under various load forces is calculated and analyzed to provide theoretical guidance for the optimization of the design.Analytical conclusions:(1) the optimized CRTS Ⅰ double block ballastless track can be applied to high speed railway and intercity railway projects;(2) the results of track structure stress calculation show that under the train load,the bending moment of the optimized track bed slab is less than that of the traditional one,and the bending moment of the optimized base is increased compared with the traditional one;the bending moment of the optimized track slab in the bridge section is larger than that of the traditional one;the axial force of the unit structural track bed under the whole temperature load can be greatly reduced.关键词
