Fig. 1 Load distribution of Shield Tunnel Segment
2.2 Material Model and Main Parameters
Shield tunnel lining is usually precast in factory and assembled in the shield tail.
In designing segments, ignoring the weakening effect of the joints leads to the overestimation of design axial force, and thus causes unnecessary cost due to extra reinforcement and material.
