Considerating reinforcement and curtain effect

flexibility coefficient of pile is obtained by means of shear displacement method. Theoretical solution between settlement and load of pile is deduced according to physical relation of pile head and pile bottom on the basis of soil layered model. Comparative result of engineering example demonstrates that the pile groups settlement computation method is feasible. Moreover

the analysis indicates that the soil layered distribution in the reinforcement area influences the pile groups settlement; the increase of soil modulus can reduce its settlement effectively.
