Abstract: Analyzing the cooperation mechanism of piles, soil and cushion，the method to calculate the stress ratio of piles to soil is introduced by considering harmony working of piles, soil and cushion in composite foundation. The factors influencing the stress ratio of piles to soil, such as cushion modulus、soil modulus of piles end, rigid ratio of pile and soil, pile length, area displacement ratio, are discussed by calculating stress ratio , and the bearing behavior of rigid pile composite foundation are analyzed.

Key words: rigid pile composite foundation, harmony working, stress ratio of piles to soil, bearing behavior
