Abstract: The characteristics of a new foundation model, consisting of 2 spring layers interconnected by a shear layer, are studied. The study is conducted on the classical problem of a foundation subjected to a rigid stamp. In order to reduce the number of foundation constants to an absolutely necessary minimum, special attention is given to a possible dependence of the constants of the upper and lower spring layers, particularly to the spring constant ratio 3 which is suggested by Reisaner's foundation model. A comparison of the obtained pressure distributions with relevant experimental data seems to support the adoption of this value, thus reducing the number of foundation constants to 2. Advantages of the presented model over other foundation models are pointed out.
