A numerical case study of stub type abutment consist of square wall pile and retaining wall has been done for its possible application. The FEM analysis using 3 dimensional elements is performed for defining its characteristic behaviors with respect to its construction sequence. The results indicate that the pre-construction of reinforced wall before installation of the square wall pile is more effective in the view point of the displacement and stress.
