摘　　要：朱亭湘江大桥桥位所在河段航道等级提升,通航船舶吨位增大。为此本文首先研究提出湘江航道2 000 t级船舶对桥墩的撞击力,然后验算该桥的抗撞能力;最后针对该桥桥墩抗撞能力较差的特点,创新性的提出了"四柱墩+钢复合材料浮式圆形防撞系统"。该系统安全可靠,经济适用,有效地解决了该桥的防撞问题。With the upgrading the class of waterway of the Xiangjiang river where the Zhuting Xiangjiang Bridge is located, the tonnage of navigable ships is gonging to increase.For the safe of the piers, this paper first studied the collision force of the 2000 tons ship on the piers,and then verified the collision resistance of the bridge. Finally, in view of the poor collision resistance of the bridge piers, the innovative "four-pillar pier+steel composite material floating circular collision avoidance system" was proposed. This system is safe,reliable and economical, which effectively solves the collision avoidance problem of this bridge.
