Abstract： The detail introduction about the material model and failure index of the element in the numerical simulation the collapse of vessel collision the reinforced concrete bridge is presented first, then the delicate finite element model for bridge superstructure, substructure and support saddle is set up, where the elastoplastic damage cap model is used for concrete and the elastoplastic kinematic hardening is used for steel bar. The numerical simulation of the collapse process of bridge structure caused by vessel collision is carried out and the collapse mechanism of continuous girder bridge is pointed out.
