This paper studies a method to identify the spring stiffness of the frame - soil structure. The model of the problem is a two-dimensional structure, linear elastic deformation, model of soil using the Winkler model (with normal, tangential spring). The problem will be solved by the penalty function method - the minimum of the objective function - combined with the finite element method. The numerical calculations show that the model, algorithm and calculation program are reliable. The program can be used to identify the spring stiffness of the frame - soil structure in two dimensions, serving to determine the actual working state of the structure, to propose solutions for reinforcement, repairing, improving bearing capacity, prolonging the life of the structure.
