【 摘 要 】

Bridge is an important transport network, and is an key target of breaking and blockade battlefield. In order to provide reference information for reinforcement scheme after damage at war, it is necessary to study damage characteristics of bridges which undertake main transportation task. The paper is to study damage Characteristics of The Bridge which is serving through numerical simulation. Create the model of cruise missile and real model of major bridge through pre-process software. Set two speed to realize contact explosion and penetration explosion; Adjust attack position and the amount of TNT. Be solved through the software LS-DYNA. Obtain dynamic response and different degrees of damage effect of certain important position of the bridge. The results can be used to provide certain reference as antiknock design of and safety assessment after damage long-span bridges.
