Abstract: Based on the analysis of composite foundation with hybrid piles in homogeneous soil,the solutions of composite foundation with hybrid piles in layered soil were deduced by introducing elastic layered medium theory,and then a relatively complete theoretical system to analyze composite foundation with hybrid piles in layered soil was built up.Numerical method was used to solve the integral equations,and the axial forces,shear forces and displacements along piles under the actions of cushion were obtained.Comparison with classical elastic solutions verified the accuracy of the presented method and calculating program.Finally,a practical engineering project was studied to illuminate the applicability of the presented method.
