Abstract

Wide tunnels,such as those with high filling, can suffer limited applicability and also reduced structural stability. Therefore, to improve these limitations of precast cut-and-cover tunnel segments, this study proposes rib reinforcement of the vaults of the precast segments. Large-sized experiments assess the effectiveness of the various rib-reinforced precast arch cut-and-cover tunnel structures, and compare them against otherwise similar non-rib-reinforced specimens. The results show that the rib-reinforced precast cut-and-cover segments are suitable for building wide tunnels with high filling.
