For the verification of the load bearing and deformation behavior of segmental lining under exactly known conditions a test rig was designed and built in cooperation between the Montanuniversity of Leoben – Chair of Subsurface Engineering and the Austrian Federal Railway. On the basis of tests performed with steel‐reinforced precast elements, first statements can be made in relation to the load bearing and deformation behaviour of the tested segments. Furthermore, a camera‐based system for crack detection is presented. A finite‐element model has also been set‐up and this model has been validated using the test data.
