摘　　要：针对明珠湾大桥拱脚部位存在被船舶甲板室撞击的风险,分别采用规范方法和数值仿真方法进行了结构抗撞能力验算,并进一步对桥梁拱脚部位进行了防撞方案设计和比选。研究结果表明,明珠湾大桥主桥拱脚部位能够满足设防船舶的甲板室抗撞性能;拱脚采用转筒式防撞设施在防撞效果和经济上具有优势,推荐该方案。In view of the collision risk of ship deckhouse at the arch foot of the Mingzhu Bay Bridge,the structural anti-collision capacity was checked by the specification and numerical simulation methods respectively,and the anti-collision schemes for the arch foot of the main pier were further designed and compared.The research results show that the arch foot of the Mingzhu Bay Bridge can meet the anticollision performance of the deck house of the ship with fortification.The use of rotary drum anti-collision facilities at the arch foot has advantages in anti-collision effect and economy,and this scheme is recommended.
