It has already been reported that damage to embankment due to earthquakes has frequently occurred on soft ground with highly inclined bottom.To clarify the influence of soil improvement upon seismic embankment response during earthquakes,two dimensional dynamic response analyses using Finite Element Method were executed for six models varying width and thickness of improved soft ground. Comparison of acceleration and displacement response characteristics and investigation on how to design the effective width and thickness of improved soft ground were done. ƒL�[ƒ��[ƒh�i‰p�j�F - ‹LŽ–‹æ•ª�F - ‹æ•ª �@�@�@ˆÏˆõ‰ï˜_•¶�W
