This paper deals with settlement of the abutment backfill due to earthquakes. A few such case histories are described. The region which comes under seismic influence is indicated by distance from epicenter and magnitude of earthquake. Some multivariate analyses is performed, and discriminant equations which distinguish between settlement more or less than 10cm are proposed using seven variables: width of embankment, SPT N‐values of embankment, height of embankment, SPT N‐values of ground surface, depth of subsurface layer, height of abutment and acceleration of ground surface. Then multiple regression equations are proposed particularly for the settlement more than 10cm. This enables us to estimate quantitatively the settlement of an abutment backfill during an earthquake. キーワード（英）： - 記事区分： - 区分 　　　　論文集
