Abstract: The contribution discusses the quantitative evaluation of design robustness through the use of a new design Index for the Capacity Utilization of Linings in Tunnels (CULT-I). This index is geometrically defined and uses a simple concept to measure the proximity of a design point to a lining capacity envelope, in this case the Bending moment-Axial force capacity limit...
