An analysis tool for on-site monitoring of the level of loading in tunnel linings is presented. It is characterized by the combination of in situ displacement measurements at measurement points (MPs) installed at the inner surface of the shotcrete lining and a realistic material model for shotcrete. The underlying shell-theory-based structural model of the tunnel lining leads to a significant reduction of the computation time and provides the robustness required for on-site applications. Recent results obtained from the application of the developed analysis tool in the course of the excavation of the Lainzer tunnel (Austria) are presented.
