This paper presents the applicability of the proposed simple estimation method for lateral displacement of the abutment constructed on soft ground. The method uses the relationship between the two non-dimensional parameters, which consider the chear strength, soft ground thickness, bending stiffness of piles, embankment load and lateral displacement of the abutment. A liner relationship between the parameters on the double-logarithm scale were confirmed according to the results of finite element analyses and the centrifuge modeling tests. Besides, the abutment displacements of 4 case studies were examined using the proposed relationships. The estimated displacements agreed well with the measured esults, and its validities were confirmed.
