The flexible-piled composite foundation is one of common processing ways to treat with soft subgrade. The parameters are discussed to improve the accuracy of settlement deformation calculation. Soil deformation parameters and misuses of settlement calculation parameters are analyzed by the theory method and finite element method (FEM). Based on the mechanism of deformation of lime-soil piles, the relationship between stress and strain of pile and soil is analyzed. Meanwhile, calculating key parameters of effective pile length, composite modulus and additional stress are proposed by the theory method. At last an engineering example is descried to explain their application.
