Pile foundation structure

Abstract

To provide a pile foundation structure capable of suppressing the occurrence of twisting behavior of the entire building by reducing differences in rigidity due to pile length while suppressing an increase in cost.SOLUTION: A large number of support piles 4 are distributed from the bottom of a foundation 2 of a building 1 to a supporting layer 3 underground. The bottom of the foundation 2 is formed so that, among a large number of support pile joint points 6 to which the support piles 4 are joined, the support pile joint points 6 located at positions where the depth from a ground surface 7 to the supporting layer 3 is relatively large are positioned deeper underground than the support pile joint points 6 located at positions where the depth from the ground surface 7 to the supporting layer 3 is relatively small.SELECTED DRAWING: Figure 1
