摘　　要：运用简化的共同作用分析方法,并将采用点弹簧模拟高层建筑下桩对筏板的作用与面弹簧模拟高层建筑下桩对筏板的作用进行对比。通过不同影响因素(有限元网格划分、弹簧属性的选择)分析筏板基础的受力及变形并得出结论以供广大工程人员参考。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.
