ABSTRACT
Digital models are often only used in the construction process of a structure and lose their meaning after completion. The goal is to continue to use these models during the operational phase and for maintenance, to generate added value from them. The continuous use of a digital model as a digital twin is a viable approach to specifically analyze the relevant structure components and simulate effects from changing conditions such as the long-term behavior of the structure. However, the development of numerical digital twins reaches its limits very easily due to a lack of information about boundary conditions or material properties and their development over time as well as the lack of suitable monitoring systems. In this study, the development of a digital twin of a tunnel profile is presented, in which analyses regarding suitable monitoring systems for the SLS and ULS behaviour of the profile were also carried out. It was also of particular interest to show the added value that can be generated by the detailed digital twin in terms of safety or safety formats.
