Abstract:A 3D finite element structural model is built in this paper to study the load-bearing behavior of stagger-jointed segmental linings of shield-tunnel and to analyze shear force transference between adjacent segmental rings. Based on the 3D analysis result, shear models of ring joint bolt is built and shear parameters between rings needed in 2D analysis with beam-spring model can be obtained by this shear model. The results of 2D analysis of shield-tunnel segmental linings have a good agreement with those by 3D finite element model. It shows that the presented shear model is effective for stimulation of shear force transference between adjacent segmental rings.
