A simplified analytical approach is proposed to study the behavior of the piled raft foundation with rigid raft subjected coupled loads in layered soils. Based on solutions of Mindlin

the interactions between pile and pile

pile and soil

soil and soil were taken into account to determine the flexibility matrix of the pile group-soil system; then the load-settlement relationship of piled raft foundation subjected coupled loads was obtained. Comparison between the results from the finite elements and the calculated results was carried out

and the feasibility of the present method for analyzing piled raft foundation is proved. Then the method is used to study the stresses and distortion characteristics of the pile raft subjected coupled loads. The numerical results indicate that the piles’ axial force and the settlement of piled raft foundation subjected coupled loads are nonuniform.
