The utility model discloses a high-energy-level dynamic compaction and replacement and pipe pile combined foundation structure for a deep and thick soil filling field. The high-energy-level dynamic compaction and replacement and pipe pile combined foundation structure comprises a foundation with the soil filling thickness smaller than 20 m and a foundation with the soil filling thickness larger than 20 m. The thickness of the filled soil is smaller than 20 m. The foundation is arranged on the geology of the filled soil and the silty clay layer. The thickness of the filled soil is larger than 20 m. The foundation is arranged on the geology of a fully-weathered or strongly-weathered granite layer. A dynamic compaction replacement foundation and a dynamic compaction pipe pile foundation are arranged in a building area at the same time so as to deal with and solve the problems of bearing capacity and deformation of corresponding geological areas and bearing foundations respectively, and the two foundations are ar
