Development of monitoring systems for geotechnical safety management during renewal measures under railroad operation
Abstract
ÖBB-Infrastruktur maintains and operates about 150 tunnel structures with an age of more than 100 years. The majority of these are masonry tunnels whose lining can be of various types (e.g. quarry stone masonry, brick masonry, concrete molds). Damage caused, for example, by aging and influences from operation as well as requirements for current clearance specifications require in part extensive repair or renewal measures on the existing masonry. These measures, some of which are carried out during ongoing rail operations, are usually accompanied by a temporary weakening of the existing tunnel vault. In this research project, monitoring systems are to be developed that can be used reliably and economically in the course of vault repairs of old masonry tunnels under tunnel conditions.
