The resistance of longitudinal joint is a crucial design parameter on the mechanical properties and structural behavior of precast tunnel segmental linings constructed by the Tunnel Boring Machine (TBM). Recently, with the increased dimensions and functions of the shield tunnel, the traditional bolted connection forms (e.g., straight bolts, inclined bolts, curved bolts) for segmental joints m…

DOT has the characteristics of special section and relatively large area of excavation face. Its propulsion will cause large formation disturbance. But too much soil disturbance usually leads to a series of environmental diseases. 3D elastoplastic FDM model was applied to analysis the dynamic construction process relying on a DOT project in Shanghai. Surface displacement field and the distrib…
