Abstract: In the numerical analysis for the soil-dam interaction, the bi-material model (on the interface, two materials possess the same lateral deformation ) is usually used, that causes error between analytical result and practice. In order to discuss the error and set the correct analytical model, the bi-material model and the bi-body model (relative lateral deformation is considered) are proposed. Besides, their samples were tested under axial compression. It is shown that the ratio of strengths ? between two materials is an important parameter for both models, but its effect and the mechanism on each model is different.

Key words: bi-material model, bi-body mode, interface, interactions, axial compression
