Based on the train dynamic vibration in-situ monitoring at the Beiluhe test section of Qinghai-Tibet Railway and the laboratory triaxial compression creep test

time hardening power function rule and Druker-Prager yield and failure criterion coupled creep model of the ABAQUS FE were utilized to simulate the creep effect of the plain fill embankment at the permafrost area of Qinghai-Tibet Railway. The results show that the time hardening power function rule and creep model simulate the time effect during operation of the railway embankment accurately; vertical displacement decreases gradually from center of embankment top to inside and both sides of the plain fill embankment. The maximal displacement reaches 14 mm in one year; and this value is consistent with the result of deformation observation in-situ. The creep strain value of center is greater than that of top and natural ground of the embankment; and the center of embankment is most influenced by train dynamic vibration.
