Abstract

In the prognosis of internal forces in segmental tunnel linings engineers face major uncertainties. This is due to e.g. the complex load-bearing behavior and simplified assumptions in calculations. It leads to an unclear reliability of segmental linings, which is unfavorable especially in challenging loading conditions e.g. due to high-rise buildings in the vicinity of inner-city tunnels. Hence, a better insight into the real structural behavior and the actual internal forces is desirable. So far no standardized or well-established structural monitoring system exists for segmental linings. This is why a new innovative structural monitoring system for long-term measurements has been developed. The monitoring system is applied to the segmental linings of a newly build inner-city tunnel. The development process, the instrumentation and the functionality of the system are presented as well as measurement results. Finally, insights into the real structural behavior gained by the measurements are given and findings are discussed.
