Abstract

Today fibre reinforced concrete is increasingly applied for tunnel construction (tunnel linings, tunnel segments). The essential benefits are e.g. the higher load bearing capacity, savings potential on the conventional bending and binder reinforcement, the absorption of splitting forces by the fibres, crack width limitation, higher durability, improved fire resistance, optimization of the workflow, etc. Beside the steel fibres carbon or glass fibres and polypropylene fibres are being added increasingly. Recent developments in concrete technology have pro - duced the Ultra-High-Performance Fibre-Reinforced-Concrete. This work examines the use of UHPFRC at the double shell segmental lining system. As reference object serves the currently constructed tunnel chain Perschling which is part of the four track west railway route extension in Lower Austria. The aim of the analysis is the design of an alternative UHPFRC shell with minimum thickness while maintaining the constraint that the deformations are not exceeding those in the tender design with its C 40/50 reinforced concrete segments.
