The presence of defects in real oil tanks plays an essential role in their accident-free operation. The majority of theoretical and experimental studies are devoted to the investigation of the effect of defects in the form of initial imperfections of the shape of thin shells on the carrying capacity and stability. Initial imperfections are the main factor that reduces the critical load. The first of the studies of the sensitivity of the critical load to the initial geometric imperfections of the form was performed by L. Donnell. A special role in the development of the theory of stability of imperfect shells was played by the asymptotic method of V.T. Coiter, which is used in J. Hutchinson. I.Arbosh, Ch.Bebkok, J.C.Amazigo and others research. Most of these papers were carried out on the assumption of linear critical behavior of the solution. In the future, for a detailed account of the imperfect geometry of nonlinearly deformed shells under an arbitrary load action, the researchers began to apply the synthesis of the reduction method and the Coiter method. At present, there are modern computational complexes that allow us to introduce initial imperfections directly as geometric parameters of the middle surface of the shells. The solution of the nonlinear problem in such formulation can more fully reflect the influence of the initial imperfections on the decrease of the critical load. However, the problem of determining the permissible failure-free operation region of tanks with real imperfections of the shape under the action of combined loading remains important. The stability of an oil reservoir with real imperfections of a wall under the joint action of axial compression and surface pressure is studied using a program complex of finite element analysis. To determine the permissible range of fail-safe operation of the reservoir, irregular imperfections of the middle wall surface are simulated as ratios of the buckling forms with different maximum amplitudes obtained in solving the problem of loss of stability by the Lanczos method. The stability of the shell with real and simulated imperfections of the wall is investigated using the nonlinear static problem by the Newton-Raphson method. Critical ratios of axial compression and surface pressure are determined to ensure overall stability of the reservoir wall. The region of failure on the stability of the oil reservoir with real imperfections is obtained.
