This paper presents the results of identification problems associated restraint system equivalent of the payment structure - pile. The model of the problem is the payment structure - pile frame as 2 dimensional, linear elastic deformation, linked deposit - should be replaced with fully supported restraint with equal depth. The problem posed be gradual approximation method (iterative method) based on fine minimize function - is the total squared error between the values measured and calculated values particular - combined with finite element method. From the numerical calculation shows, models, algorithms and calculation program are reliable.
