| Abstract: | This paper adopts the simplified method which uses the vertical springs or cover springs instead of the piles under the raft of the piled raft foundation in a super high building and considers the interaction between the piled raft foundation and the superstructure to calculate the moment and the deformation of the foundation and the internal force of the raft.With different influence factor of pile raft foundation,the effects of the raft behaviors were analyzed.In the end,the conclusions as useful references were obtained. |
