Abstract: This paper not only presents the valuable field experimental data,but also demonstrates the analytical results on settlement,earth pressure,loads on pile group,loads on mega columns and stress in raft,especially,the influence of structure stiffness on stress in raft,the contribution of number of storeys of structure stiffness to foundation and its contribution limit.Meanwhile,in order to provide a new reform for the design of piled raft,a real theoretical and practical method is also given.Besides,some suggestions on settlement prediction and loads on pile group are proposed in this paper.
