Calculation of nonlinear elastic foundation under an inhomogeneous beam slab is a type of contact problems of nonlinear elasticity theory. The variation-difference approach (GRP) (modification of the variation method — in a nonlinear formulation and the method of finite differences) is used. The proposed approach is allowed to fully describe the stress-strain state (SSS) nonlinear elastic foundation, to investigate the contact zone of slab — base, to calculate the base precipitation and internal forces in the beam plate.
