Abstract
It is well known that landform influences the behavior of the ground during earthquakes. The objective of this study is to clarify the effect of a slope on the dynamic properties of diluvial terrace based on ground investigations, seismic motion observations and twodimensional finite element analyses, by choosing a target area that has a landform typical to the southern Kanto plain in Japan. Through the study, the followings were found: (1) Due to a weak soil along the slope, amplification becomes very large, but the area of influence is relatively small. (2) Amplification due to ground irregularity itself is relatively small, but the area of influence is fairly large. (3) It should be noted that the possibility of slope failure during an earthquake becomes very large at the slope when a weak soil exists along the slope.
