Abstract:
In the loess region, the exeessive setllement and difierential setlement, slope instability, oceur fre.quently on the embankment, especially on the asymmetrie embankment. In this paper, the dynamie behaviorsof the asymmetrie unreinforeed, reinforeed with geogrid or EPS embankment were studied through numeriealsimulation eonsidering the elfeets of traffie load of eoal trucks and regarling the traffie load as semi-sine wave.Parametrieal analysis was also condueted eonsidering the amplitude, frequeney of trafie load and the intervalbetween trueks. The results showed that the amplitude and frequeney of traffie load had great efleels on the de.formation of embankment, while the interval between trucks was of less effeet. The reinforeement eleet of geo-grid was always better than EpS.
