Deformation Behavior and Dynamic Stress Response of High Railway Embankment under Cyclic Load

Du, Yong-Li / Lin, Yu-Liang / Yang, Guo-Lin

The deformation of railway embankment is strictly controlled to ensure the safety of train running. In order to study the engineering behavior of railway embankment, simulation analysis on railway embankment with height of 8 m was carried out. Dynamic loads with amplitudes of 0∼50 kPa and 0∼100 kPa were imposed. The deformation behavior and dynamic stress response of embankment were studied. The results show that the embankment presents attenuation effect on dynamic stress. The static earth pressure near the top of embankment is enhanced, and the static earth pressure at the bottom of embankment is released. The increase of train load will change the failure mode of embankment. The deformation mode of embankment is in subsidence mode when the amplitude of dynamic load is 0∼50 kPa, and deformation mode turns sliding mode when amplitude is 0∼100 kPa.
