摘　　要：板桩防波堤是一种对深厚软土地基有较高适应性的防波堤结构,目前国内外应用较少。以某海外板桩防波堤工程为例,采用不规则波对不同水深处的防波堤断面开展设计波浪要素断面试验,判断护底块石、沙垫层稳定性,测量模型越浪量和防波堤迎浪侧所受波浪力分布,验证防波堤结构的安全性和合理性。最后将试验结果与国内外规范公式计算结果进行对比研究。结果表明,试验得到的波浪力及越浪结果偏于安全,防波堤设计高程合适;不同波浪状态下规范公式计算结果与试验值之间的差异不尽相同,进行具体工程设计时,需将规范公式计算与物理模型试验结合,力求设计参数合理,保证防波堤自身结构及掩护港区的安全性。Sheet pile breakwater is a type of breakwater structure with high adaptability to deep soft soil foundation,which is seldom used at home and abroad.By taking an overseas sheet pile breakwater project as an example,designed wave element section tests were conducted with irregular waves on sections at different water depths,to judge the stability of the bottom protection stones and sand cushion,and measure the amount of overtopping flux and the wave force distribution on the wave-facing side of the breakwater to verify the safety and rationality of the structure.Finally,the test results were compared with the calculation results of domestic and foreign design code formulas.The results show that the wave force and overtopping results obtained from the test are on the safe side,and the design elevation of the breakwater is suitable.The difference between the calculation results of the design code formulas and the test values under different wave conditions is different.When designing specific projects,it is necessary to combine the calculation of the design code formulas with the physical model tests,and strive to make the design parameters reasonable to ensure the safety of the structure of the breakwater itself and the protected harbor area.
