Abstract
This chapter presents two examples of reliability analyses in mechanized tunneling. The first example shows the capabilities of numerical reliability analysis in a tunnel project’s design stage. The second example presents a hybrid surrogate modeling approach for real-time predictions of interval settlement fields. For real-time reliability analyses, fast results are required, which numerical efficient surrogate models achieve based on the finite element model and monitoring data. The chapter also presents approaches for reliability analyses in mechanized tunneling, which can be applied in tunnel projects’ design and construction phases. The numerical reliability analyses are based on a process-oriented finite element simulation model. The application simulation-and-monitoring-based assistant for real-time steering in mechanized tunneling is a helpful tool for decision making related to adjusting the support and grouting pressures during tunnel construction.
