    Effects of anti-pull ties on the bearing behaviors of shallow tunnel-type anchorages in soft rock

    Tunnel-type anchorages (TTAs) installed in human gathering areas are characterized by a shallow burial depth, and in many instances, they utilize soft rock as the bearing stratum. However, the stability contro...
