Full Article:

This paper adopts the finite element method (FEM) to calculate an example of a 25-storey frame-tube structure by considering the interaction of superstructure, foundation and ground. The analysis of the effects of site factors on the stress and displacement of the raft foundation is carried out. The main site factors include: constraint effect of the surrounding ground soil, influence of neighboring buildings, and effect of the construction defect of cushion. The study shows that 1) the geometry size of ground soil has relatively great influence on the stress and displacement of the raft foundation, the influence sphere is about 2~3 times the geometry size of the raft; 2) neighboring buildings have a more significant effect on the stress and displacement of adjacent edge of the raft, this effect gradually disappears with the increase of building spacing; 3) the construction defects of cushion have limited effect on the stress and displacement of the raft.
