Research on Horizontal Bearing Capacity of Precast Thin-Wall Steel and Spun Concrete Composite Pile

Abstract:

Precast thin-wall steel and spun concrete composite pile (TSC pile) is a new type of steel-concrete composite foundation pile whose performance is between steel pile and concrete pile. 3D numerical analysis model of TSC pile was established by FEM software in this paper. By compared with the laboratory bending test results, the model’s reliability was verified, and then the bearing capacity of TSC pile under horizontal load was calculated, moreover, influences of different cross section parameters (diameter, wall thickness, steel pipe thickness, pile’s length) on the horizontal bearing capacity of TSC pile were studied. The results show that: with the increase of pile’s outside diameter, wall thickness of steel pipe, wall thickness of concrete pipe and length of pile, the horizontal bearing capacity of TSC pile is increased. The outside diameter has a biggest impact on the horizontal bearing capacity of TSC pile, then pile’s length, steel pipe’s wall thickness, and the influences of concrete pipe’s wall thickness are the least.
