Calculation for Settlement of the Raft on Rigid Pile Composite Foundation
-
摘要: 采用一种桩-土体系共同作用的解析解考虑刚性桩复合地基，该解析解以剪切位移法为基础，进而通过其与垫层、筏板的相互作用计算筏板基础的沉降。用自编程序对算例计算的结果与ANSYS计算的结果进行对比，并与工程实测进行对比，结果吻合较好，表明该方法可行，有应用前景。Abstract: The rigid pile composite foundation is simulated by an analytical expression of pile-soil system, which is based on shear displacement method. Then, the settlement of the raft by considering the interaction of the rigid pile composite foundation, the cushion and the raft are caculated. The results calculated by the program agree with the results obtained by ANSYS and on-the-spot survey, which shows this method is practical and applicable.
