The technology of the composite ground under a flexible foundation have been widely used in transportation, water conservancy and other departments, yet its theory of characterizing the behavior of the composite ground needs to be further researched. A simplified analytical model is presented, considering the above four parts which includes the flexible foundation, the cushion, the composite ground, and the underlying soils as an interactive system, allowing for the relative movement between piles and soils, and assuming different settlement of foundation soil at the same elevation. The force equilibriums of a typical element are established. And then, according to the compatibility of stress and deformation on the interfaces between these four components, the formulas on settlement and stress ratio of pile-soil, which is used to characterize the behavior of the composite ground, are derived.
