Abstract: Composite foundation with rigid-flexible piles under strip foundation is analyzed by means of finite element method on the basis of field test．The influential factors including cushion, cap, rigid pile and flexible pile on deformation characteristics of composite foundation with rigid-flexible piles are studied systematically. The results indicate composite foundation settlement reduction along with cushion thickness reduction and module increment, cap thickness increment is advantageous to differential settlement reduction, rigid pile is main component to control settlement; flexible pile increment can reduce differential settlement. These conclusions are helpful for optimum design.

Key words: composite foundation with rigid-flexible piles, finite element method, settlement, optimization of design
