The invention discloses a composite foundation bearing structure for placing a prefabricated pile into a cement-soil mixing pile. According to the composite foundation bearing structure for placing the prefabricated pile into the cement-soil mixing pile, the cement-soil mixing pile is constructed according to the distribution range of the prefabricated pile on the bottom face of a cushion cap or raft foundation or box type foundation of a building foundation and the prefabricated pile center position, an auxiliary material and/or an additive are/is mixed in cement-soil curing agent preparationslurry of the cement-soil mixing pile, then a reinforced concrete prefabricated pile is placed into the corresponding cement-soil mixing pile, and the top of the prefabricated pile is provided with areinforced concrete cushion cap or a raft foundation or a box type foundation. By means of the composite foundation bearing structure, the cement-soil mixing pile and the reinforced concrete prefabricated pile are organically
