摘　　要：文中分析了某挡浪墙后置形式的深水直立式防波堤波浪荷载特点,采用中国规范、修正的合田良实公式、森佛罗简化法公式的波压力理论进行计算,并与断面物模、局部整体物模的波压力试验结果进行对比,分析差异。提出当相对水深较大时,采用中国规范的推荐公式更能合理地模拟波压力曲线,并提出对中国规范波压力计算方法选取的建议。针对后置的挡浪墙进行波压力分析,推荐了新的波压力计算方法,推荐当防波堤顶部无越浪要求且需要改善港池泊稳环境的情况下采用该方法,可以改善结构受力。The wave load characteristics of a deep-water vertical breakwater with a posterior wave wall were summarized and analyzed,the wave pressure theory of the Chinese code,the modified Goda formula and the Sanflou simplified formula were used for calculate,the calculation is compared with the wave pressure test results of section physical models and local integral physical models,and the differences were analyzed.It is proposed that when the relative water depth is relatively large,using the recommended formula of Chinese code can more reasonably simulate the wave pressure curve,and suggestions are made for the selection of Chinese code wave pressure calculation methods.A new wave pressure calculation method is recommended for the wave pressure analysis of posterior wave walls.It is recommended to use this method when there are no wave crossing requirements at the top of the breakwater and the mooring stability of the harbour basin needs to be improved,which can improve the structural forces.
