Conclusions
1. For the first time, the methods of the theory of elasticity and the theory of limiting equilibrium have been used for establishing the curvilinear nature of the relations S=f(P), which corresponds to the nature of this relation observed in tests with trial loads.
2. For all cases of embedment of the plate and for loads substantially smaller than the limiting loads, the contact pressure diagrams are similar to those obtained by the theory of elasticity, but do not exhibit any special characteristics under the edges. This agrees with the results of experimental investigations carried out in order to determine the contact pressures.
3. The plate displacements, for all other conditions being equal, and also for loads exceeding 0.3 MPa, depend substantially on the relative embedment of the plate in the soil or on the soil cohesion.
4. For practical analyses, the relation S=f(P) obtained by solution of the elastoplastic problem can be approximated by a hyperbola.
