Abstract	Column–supported embankment is usually constructed on weak foundation in order to reduce total settlement and accelerate construction process. In this study, a simplified model is carried out to study the load transfer mechanism for this kind of embankment. To evaluate the differential settlement between the column and the surrounding soil, a shape function is used to simulate the deformation of the column-reinforced foundation. As the differential settlement would stimulate the movement of embankment fill, an inner cylinder above the column and a hollow cylinder above the surrounding soil are assumed to model the embankment fill. Soil volume continuity and stress continuity are considered between the embankment fill and column reinforced soft foundation. The feasibility of the proposed method is verified by comparing the results with a two-dimensional finite element model. Some factors influencing the behaviour of column-supported embankment are investigated. When the modulus ratio between the column (Ec) and surrounding soil (Es) becomes larger, the stress ratio between the column (σc) and surrounding soil (σs) will increase (Figure 1). Similar tendency is found with an increasing ratio between the column spacing (do) and diameter (di). By capturing the main features of the col
