In the article, the authors analyze the influence of inhomogeneity of subgrade zones on the stress-strain state of the unique reservoir RVSPK-100000. For the study used numerical methods in mechanics of solid deformable body, in particular the method of finite elements. The dependences of change of equivalent stress in structures bottom, front and additional stiffening rings RVSPK-100000 fr om the height of the wall, and the dependence of the value of the lim it on the length of the tank SAG.
