摘要
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.
