Correct formulation of the differential equation system for equilibrium conditions of subsoil, especially in terms of controlled numerical calculation, is discussed. The problem of solution stability is also considered. The solution of problems, which are ill-posed, have no practical value in the majority of cases and in this way the engineering prognosis can lead to a real disaster. The object of this paper is quite relevant if its application is taken into account. Numerical calculations of boundary value problems must often be performed as true predictions. Unfortunately, the ability to submit a reliable prediction seems to be lacking in geotechnical engineering. Several reasons, which may be responsible for this disappointing state, are described.
