N2 - The bearing and deformation behaviour of segments for mechanized tunnelling and their degree of utilization are being investigated at the Chair for Subsurface Engineering at the Montan University Leoben in Austria in close collaboration with the ÖBB Infrastruktur AG. Tests and numerical modelling as well as deformation measurements in situ serve to optimize the precast concrete parts. A new test stand for biaxial tests on suitable segments was devised for the tests and equipped with the appropriate measurement technology for measuring deformations. This report presents the test stand and initial test results.
