• Composite foundation
• Cushion
• Mohr Coulomb model
• Pile group with raft
• Stress ration of piles and soils

According to the property of the composite foundation, the adjustment procedure between piles and soil and the functions of the cushion are analyzed. The effects of the cushion of the composite foundation with pile group are simulated by finite element method, and the stress ratio of piles and soils is computed with various thickness of the cushion.
