Abstract： Based on strong motion tests on typical embankment at Beilu River segment along the QinghaiTibet Railroad, the acceleration history waveforms near railway tracks were collected when the train was passing, and the dynamic train load was converted into equivalent creep stress by using the equivalent static force method. Moreover, the creep equation of frozen soil was introduced according to the result of frozen soil rheological triaxial tests. The longterm deformation of the embankment at the train load was obtained, and the ratio of permanent deformation at the train load to the whole embankment deformation was quantized as well. The research results show that the vibration effect of repeated train load on deformation accounted for approximately 10% of the total accumulative settlement of the embankment. The creep strain values at the slope toes are significant and extended upwards gradually, which increases with the development of time and the strain rate decreases instead.
