In this study

the seismic ground motion of the scarp topography under inclined P waves was analyzed using numerical simulation method.The effects of the incident degree

the slope angle

and the incident direction of seismic ground motion were discussed as well.It is found that from the bottom of scarp to the top

the amplification factor increased gradually

whereas it had no influence on the incident degree

the slope angle and the incident direction.When the incident degree was constant

the amplification factor of the scarp upside region was greater than that of the scarp downside region

regardless of the incident directions.At the same time

the amplification factor at the crest of the slope increased with the increase of the slope angle.When the slope angle was constant and the waves travelled away from the slope

the amplification factor of x component increased

while the amplification factor of z component decreased with the increase of incident angle.The results show that for waves travelling into the slope

the maximum amplification factor is generally found around the crest of the slope.For waves travelling away from the slope

the maximum amplification factor shifted from the slope crest.Moreover

the larger the slope angle

the farther the departure.The amplification factor of x component was larger for waves travelling away from the slope as compared to waves travelling into the slope

but the amplification factor of z component had no obvious change with the incident direction.
