Comparative Analysis of Single Belled Wedge Pile with Conventional Piles under Lateral Load

Abstract

A new belled wedge pile, which can improves the friction of pile shaft, tip resistance and reduce the influence of negative skin friction, was developed. The analysis model of single belled wedge pile embedded on soft soils was built by p-y curves method via LPILE software, models of conventional belled pile, tapered pile, and uniform section pile with the same volumes were also built for comparative analyze. The performances on load deflection curves, and bending moment distributions for these four pile types were comparative analyzed and discussed. Then the parameter studies of single belled wedge pile are carried out. The results show that belled wedge pile is one of cost-effective piles, which can improve lateral bearing capacities effectively.
