ZWP - Verification of the long-term properties of intermediate plates

Project: Research project

Project Details


The effectiveness and serviceability of the installed ZWP is to be verified by means of subsidence measurements in the open area as well as in the tunnel. In addition, the measured ZWP are to be removed afterwards in order to subject them to static and dynamic stiffness measurements in the laboratory. Since the initial tolerances can be up to cstat +/- 15%, discussions must be held in advance with the manufacturer and the available data clarified. On the basis of these findings from laboratory and track measurements and the comparison with the existing measurement data of the EM250, a recommendation for the age-related replacement of these elastic elements is to be made.
