中文摘要：
为有效实现桥墩的防撞设计,提出并研究了钢-CFRP组合式防撞箱的防撞性能,结合结构振动理论和数值仿真方法,分析了船桥碰撞过程中桥墩所受撞击力及其位移响应,并进一步开展了裸墩、钢防撞箱、钢-CFRP组合式防撞箱等的防撞性能对比研究.结果表明,钢-CFRP组合式防撞箱在减少桥墩撞击力和撞击位移等方面的防撞性能均优于钢防撞箱.
英文摘要：
In order to effectively realize the anti-collision design of the bridge pier, the anti-collision performance of steel-CFRP combined with the anti-collision box is proposed and studied. Based on the structural vibration theory and numerical simulation method, the impact force and displacement re- sponse of bridge pier are analyzed. Furthermore, the comparative study on the anti-collision perform- ance of the bare pier, steel anti-collision box and steel-CFRP combined anti-collision box is carried out. The results show that the anti-collision performance of the steel-CFRP combined box is better than that of the steel anti-collision box in reducing the impact force and the displacement of the pier.
