The concrete ring beam at the entrance of subway station is generally connected with the tunnel segment by bolts. The bolts are often embedded in the ring beam of subway station, and there is bond-slip deformation between the bolts and the concrete wrapping them. This may have an impact on the opening width of the ring joint and the damage development of the ring beam structure. Based on the existing constitutive model of bond-slip between concrete and steel, a high-precision finite element program function was utilized to investigate the concrete nonlinear behavior and cracking mechanism, and a model describing the behavior of bond-slip mechanism was built up to measure the influence of the slip displacement on the width of ring gap. For three different types of connection bolts with long anchorage and short anchorage, simulations were performed to analyze the bond-slip behaviors of these bolts in the ring beam concrete and the width increasing of the gap between ring beam and segment. Meanwhile, through quantitative analysis of distributions of bond stress and bolt stress along the bolt length, the mechanism for the contribution from the displacement and deformation of connecting blots to the width increasing of the gap was revealed. Results show that the bolt connection stiffness derived from the bond-slip models is between those derived from the completely fixed model and the spring model, and the influence of the bond-slip deformation on the width of the annular gap between the shield segment and the station ring beam cannot be ignored. In the case of long anchorages, the contribution of bond-slip to the gap width can reach up to about 30% when the bolt begins to yield. After the bolt yields, the slip proportion will decrease to less than 8% with the expansion of the circumferential seam. Affected by this, the tensile stiffness of the bolt considering bond slip is at least about 1/3 of the fully fixed model
