Abstract: The interaction analysis of structure-foundation-soil was used in the process of the foundation design in north region of Sanlitun SOHO, and the difference of subsoil defonuation and the resistance of the raft foundation under water buoyant force were especially studied. Through those analyses, it was confinued that the raft natural foundation can satisfy the design requirements and it is feasible to use the raft natural foundation iIl this project.
