Rigid-flexible pile composite foundation for reducing soft foundation settlement under rigid foundation

The invention discloses a rigid and flexible pile composite foundation capable of reducing soft foundation settlement under a rigid foundation. The structure comprises a flexible cushion layer, rigid piles and flexible piles, the flexible piles are arranged on the periphery of the outer contour of a rigid foundation in a grid shape, the rigid piles are arranged in the middle of the flexible piles, the flexible cushion layer is arranged on the tops of the flexible piles and the rigid piles, and the rigid foundation is arranged above the flexible cushion layer. The defects that in the prior art, the manufacturing cost is too high due to the fact that rigid piles are purely adopted or the settlement control requirement cannot be met due to the fact that flexible piles are purely adopted are overcome; the method has the advantages of improving the bearing capacity of the foundation, effectively reducing settlement, and being safe, reliable, economical and reasonable. 本发明公开了一种减小刚性基础下软基沉降的刚柔桩复合地基。它包括柔性垫层、刚性桩和柔性桩，所述
