PROBLEM TO BE SOLVED: To provide a method of constructing a reinforced soil abutment and a pier, which facilitates maintenance of a bridge, simplifies the structure of an anchorage portion, and contributes to cost reduction, and to provide structures of the reinforced soil abutment and the pier. SOLUTION: According to the method of constructing the reinforced soil abutment and the pier, (a) a finished thickness of each layer of gravelly soil (cement stabilized soil) 2 such as size-regulated debris mixed with cement is set to 50 to 15 cm, and each layer is rolled such that a compaction degree is set to 90 % or more, (b) followed by arranging a tensile reinforcing member 3 on each finished surface. Then (c) the steps of (a) and (b) are repeatedly carried out until the layers are piled up to a predetermined height, to thereby construct a reinforced mound body. Further (d) a small abutment 6 is set on an upper portion of the piled-up reinforced mound body, for mounting thereon a bridge girder 7, and then (e) cast-in-place concrete wall works 5 are set on an open surface of the reinforced mound body.
