Abstract Considering the influences of rigid pile length，flexible pile length，rigid pile modulus，flexible pile modulus，soil modulus and replacement ratio on composite modulus of composite foundation with rigid-flexible piles，composite modulus is deduced according to shear displacement method on basis of certain hypotheses. The relationship between parameters and composite modulus is analyzed. Case study shows that the new method is more precise than traditional methods，and there is a reasonable agreement between theoretical solution and measurement result.
