摘　　要：总结了国内外计算船撞力的公式,并以广东一处桥梁为例,通过经验公式和有限元数值计算得到桥墩防撞的一些设计参数,将数值计算结果与经验公式计算值进行比较,结果表明:数值分析结果小于各经验公式计算值,与欧洲规范较为接近,其中,按中国《公路桥涵设计通用规范:JTG D60—2015》以漂流物来计算船撞力是不可靠的,无法对防撞设施设计提供有力参考。针对大桥的特点,设置浮动式结合固定式钢覆复合材料防撞设施,与传统防撞设施相比,缓冲能力强,能承受更大的撞击力,耐久性更强,可为类似工程设计提供参考以期为类似工程设计提供借鉴与参考。Summarizes the formula for calculating the ship impact force at home and abroad,and takes a built main bridge in Guangdong as an example,through the empirical formula and finite element numerical calculation to get some design parameters of bridge pier collision avoidance,and compare the numerical calculation results with the empirical formula calculation values,the results show that the numerical analysis results are less than the empirical formula calculation values and European norms are closer,among them,according to the Chinese“highway code”to calculate the drifting material.The ship impact force is unreliable and cannot provide a strong reference for the design of anti-collision facilities.In this paper,for the characteristics of the bridge,set floating combined with fixed steel over composite collision avoidance facilities,compared with the traditional collision avoidance facilities,the buffering capacity is strong,can withstand greater impact force,durability is stronger,can provide reference for similar engineering design in order to provide reference and reference for similar engineering design.
