Abstract

Our procedure, developed from considerable experience, promotes an engineering approach to design and construction of tunnels. In the pre-construction phase support concepts are based on Rock Mass Behavior Types developed from Rock Mass Types and influencing factors. The System Behavior describes the rock mass-support interaction which is based on numerical simulations and previous experience (data base knowledge). During construction geological face mapping, geotechnical monitoring, and observations allow the support and excavation methods to be finalized. The observed and predicted behavior are compared by
evaluating displacement monitoring, support utilization, and overbreak volume. Deviations between the observed and predicted behavior lead to a reevaluation of the process resulting in modifications to the support and excavation methods. Our experience shows that this procedure, demonstrated by two case studies from the Austrian Alps, contributes to the optimization of tunnel construction.
