Abstract:
The deformation characteristics and overall stability of high embankment under traffic load havebeen widely studied in recent years. Based on numerical simulation method ，the response of embankment un-der dynamic uniform loads acting on the embankment surface is studied. Finally , the impacts of traffic loads’amplitude，frequency and running interval on the embankment response are analyzed. According to the re-sults , the settlements of embankment surface under dynamic traffic loads grow with the cycle index, but the in-crease percentage of deformation diminishes gradually to a stable value. The maximum settlement of embank-ment surface increases with the increment of traffic load’ s amplitude,frequency and the decrement of runninginterval.
