To address the challenges of low efficiency and high safety risks in manual steel arch installation during Tunnel Boring Machine (TBM) construction, this study proposes an innovative steel arch ...

New multicore optical fibers have many times the signal-carrying capacity of traditional single-core fibers, but their use in telecommunications has been severely restricted because of the challenge ...

The manual splicing of steel arches in Tunnel Boring Machine construction is notoriously inefficient, hazardous, and quality-inconsistent, posing a significant bottleneck to tunneling automation. To ...
