Abstract: According to the precise level survey on the subsidence of CFG pile composite foundation and the nonlinear fitting trend analysis, the nonlinear relationship between composite foundation subsidece and time was obtained. The properties of creep and uneven subsidence were pointed out under the effect of building deadweight. The importance of harmony between structure and foundation deformation was emphasized in the subsidence
