Shell deformation when backfilling soil‐steel structures of corrugated sheet is substantial and can be controlled using geodetic techniques. Typically, crown deflection is observed, which is subject to significant changes during the backfilling process. In the initial phase of the construction, the shell undergoes uplift followed by reduction. The paper analyses changes to the curvature radius as a function of the vertical displacement of the shell crown. A characteristic graph is thus created to assess the safety of the shell (and the structure) both during construction (as in the paper) and exploitation. The paper presents an algorithm of structure safety assessment based on shell deformation.
