Abstract Research purposes: Taking the high-speed railway line of a three-span continuous beam bridge with a main span of 48 m+80 m+48 m, two simply supported approach bridges on each side and 200 m long roadbed as the research object, using CRH3, CRH2C and CRH380A, with German low interference spectrum (German spectrum) and Chinese ballastless track spectrum (Chinese spectrum) is regarded as the initial track irregularity, the track irregularity caused by the settlement of the side pier of the continuous beam obtained by the mapping relationship is regarded as the additional track irregularity, and the running performance of different types of high-speed railway trains under excitation of different track irregularity spectrum is evaluated respectively.
Research conclusions: (1) The calculation results of the dynamic model of vehicle-rail-continuous beam bridge are in good agreement with those of the literature model. (2) The Chinese ballastless track spectrum is obviously better than the German low interference spectrum in comfort, stability and safety. (3) Under the initial track irregularity, the influence on security is in the order of CRH380A > CRH3 > CRH2C, the influence on comfort is CRH3 > CRH380A> CRH2C, and the influence on stability is CRH3 > CRH380A > CRH2C. (4) Under the additional track irregularity, the influence on security and comfort is the same as the initial track irregularity, and the stability varies greatly with the settlement value of the side pier. When using the German low interference spectrum, the influence on stability is in the order of CRH3 > CRH380A > CRH2C, and when using the Chinese ballastless track spectrum, the influence on stability is in the order of CRH2C > CRH3 > CRH380A. (5) The research results can provide some reference for the design and checking of continuous girder bridges with main span in high-speed railway lines.

Key words： high speed railway continuous girder bridge mapping relationship dynamic index track irregularity spectrum
