This paper describes the application of the combined rheological model to study the solution of the deformation of the peripheral wall of a cavern excavated with time under the influence of two-dimensional ground pressure in a viscoelastic formation. The concept of equivalent initial ground pressure is used under the action of three-dimensional ground pressure. The calculation formula for the deformation of the cavity wall. The method and example for the feedback analysis of the elastic displacement, creep displacement, initial displacement and final value from the radial displacement observation data of the wall are introduced.
