The effect of longitudinal deflection on shield tunnel convergence was studied through longitudinal shear transfer and circumferential flattening. Taking the typical deflection pattern of shield tunnel as example, the effects of flattening and longitudinal shear transfer on tunnel convergence and internal forces were analyzed and compared, respectively. The results indicate that the internal forces and tunnel convergence induced by the longitudinal transfer effect are normally larger than that induced by the flattening effect. However, the effect of flattening on tunnel convergence is not ignorable with the increase of tunnel settlement.
