PROBLEM TO BE SOLVED: To provide a bearing structure for a foundation pile, which has a high tip bearing force, and to provide a method for constructing the bearing structure for the foundation pile, which is good in workability. SOLUTION: The bearing structure for the foundation pile is formed of a steel pipe pile having a projection with a height of 6 mm or more on the periphery of a tip portion, and a foot consolidation column which is formed in a bearing layer in the ground or in a section inclusive of the bearing layer, and allows the tip portion of the steel pipe pile to be inserted therein in one body. In construction of the bearing structure for the foundation pile, the height H of the foot consolidation column is preferably set to one or more times a pile diameter D1 of the steel pipe pile and five or less times the same. Further, the diameter D2 of the foot consolidation column is set to a range from 1.2 to 2.0 times the pile diameter D1 of the steel pipe pile.
