CULT-I

The concept CULT-I (Index for capacity utilization of linings in tunnels) is introduced in the following scientific paper:
      Published in: Geomechanics and Tunnelling 9 (2016), No.2
      Title: Performance indicator of tunnel linings under geotechnical uncertainty
      Authors: Spyridis, Panagiotis; Konstantis, Spyridon; Gakis, Angelos
