摘　　要：通过资料调查、实地检测和理论分析对牛湾特大桥的通航安全状况进行评估。具体工作包括桥区附近水文地质数据的收集、船舶撞击力的计算、船舶撞击风险估计等。评估结果表明,牛湾特大桥存在通航净空不够、通航船舶吨位过高及船舶交通秩序混乱等风险。The navigation condition of the Niuwan Bridge has been evaluated in this article through data survey,field testing and theoretical analysis.Specific work includes collection of hydro geological data near the bridge,calculation of ship impact force and risk estimation of ship impact events.The final evaluation results have shown that the Niuwan Bridge is at risk of inadequate navigation clearance,excessive tonnage of navigable vessels and chaotic ship traffic order.
