摘要：	Crushed stone grouting pile is a new composite soft-base processing technology that combined the gravel pile with grouting technique.The design theory of controlling deformation is more reasonable than that of controlling bearing capacity during the design of the composite foundation.The transmission pattern of load,the characteristics of settlement and the influence factor of composite foundation borne with crushed stone grouting pile with rigid roof bearing plate were analyzed by FEM program,while the rule and the degree of the effect of these factors-such as capping plate replacement ratio,pile replacement ratio,diffusing zone replacement ratio,pile-soil module ratio and serous-soil module ratio-to the composite foundation settlement were discussed in this paper.The conclusions of great significance in guiding were derived,and it was expected to enriches and improves the theory and technology of settlement of composite foundation
