Realistically predicting the internal forces of segmental linings is challenging due to their complex load-bearing behaviour. Consequently, there are uncertainties regarding whether and how well the predicted internal forces correspond to the actual ones, which, of course, is undesirable. Investigating these uncertainties requires precise knowledge of the actual load-bearing behaviour of segmental linings. This can be achieved through in-situ measurements. Such measurements were exemplarily carried out for a long-term structural monitoring of the segmental lining of the extension of the U5 metro line in Frankfurt (Main) On the one hand, this allowed for a deep analysis of the real load-bearing behaviour. On the other hand, the structural monitoring provided the data needed for further investigations in the context of the aforementioned uncertainties. This paper provides an overview of the insights gained.
