摘　　要：针对大型集装箱船靠泊码头时产生的水流力进行研究,分别依据JTS 144-1—2010《港口荷载工程规范》、英国BS 6349-1规范对水流力的计算方法及公式中采用的相关系数做了无因次化比较。结合工程实例,应用OPTIMOOR软件对大型集装箱船舶在不同流向角下的水流力进行计算和模拟。结果表明:1)水流力的大小对相对水深比非常敏感。2)英标计算得出的横向水流力结果大于国标计算结果,而英标计算出的纵向水流力计算结果远小于国标。3)应用国标计算水流力时,船舶水下部分垂直和平行水流方向的投影面积需要修正。The current force generated by large container ships when berthed at the jetty is studied.By discoursing the formula in JTS 144-1-2010 Load Code for Harbor Engineering and formula in British Standard BS6349-1,a dimensionless comparison about the calculation method of current force and the related coefficients is carried out.Combined with engineering examples,the OPTIMOOR software is used to calculate and simulate the current forces of large container ships under different current angles.The results show that:1)The current force is very sensitive to the relative water depth ratio.2)The transversal current force calculated by the British Standard is greater than the calculation result of the national standard,while the longitudinal current force calculated by the British Standard is much smaller than the national standard.3)When the national standard is applied to calculate the current force,the projected area of the vertical and parallel water flow directions of the underwater part of the ship needs to be corrected.
