    Abstract
  • In order to study the influence of bolt parameters on bolt failures and segments when a derailed high-speed train impacts a shield tunnel, a numerical model of division assembling the segmental lining of a shield tunnel was established using the finite element software ABAQUS. The contact effect of joint concrete and the connecting effect of joint bolts were simulated approximately by the contact element and the connector element, the latter of which characterises the tensile, shear and flexural stiffness. The failure of bolts with different diameters and strengths was investigated using the impact load curve of a train with speed of 200 km/h and oblique angle of 12.5°. The results show that joint bolts mainly underwent tensile failure and shear failure, and the tension and shear forces of the bolt decreased to zero after the failure. Bolt failures generally appeared in succession according to the direction of train travel. Tensile failure usually occurred at the rear longitudinal bolt of the impacted segment, while shear failure usually occurred at the circumferential bolt and the front longitudinal bolt of the impacted segment. The failure time of the bolt was delayed as the bolt strength grade or diameter increased. The maximum displacement of the impacted segments under different bolt parameters was approximately 6 cm. Increasing the strength grade and the diameter of the bolt would reduce the area and the maximum value of the final displacement of the impacted segment. However, the reduction of the maximum value of the final displacement was within 10%, which means that changing the parameters of the bolt cannot significantly reduce the final displacement of the segment.
