| Abstract: | The development of compound foundation with variable rigidity is reviewed. According to the feature of base reaction, three types of soil treatment schemes under rafts are researched with finite element method. Influence of soil treatment on maximum settlement and differential settlement of foundation as well as bending moment of raft is analyzed. From an economical point of view, an optimal scheme of ground improvement with variable rigidity for minimizing the differential settlement of foundation is put forward,which may be a guide to design of actual projects. |
