摘　　要：半直立半斜坡式防波堤凭借“一堤多用”的结构优势广泛应用于防波堤工程中。外侧斜坡式结构对风浪适应性强,对波浪有一定的遮挡效应;内侧直立式结构可兼做码头,实现系靠泊及平台作业功能。目前规范关于半直立半斜坡式防波堤的研究较少,斜坡堤的消浪效果及波浪力折减系数缺乏理论支撑。结合工程实例,通过物理模型试验进行验证,将实测波浪数据分别与规范中直墙式建筑物墙前波浪力计算值、斜坡式建筑物顶部挡浪墙波浪力计算值进行对比,分析两种计算方法得出的结论与模型试验结论之间的差异并提出不同部位波浪力折减系数取值,通过波浪力试验实测值进行结构稳定性复核验算并给出相关建议。研究成果可为类似项目提供参考。The semi-vertical and semi-sloping breakwater is widely used in breakwater project because of its advantages of“multi-purpose of one breakwater”.The outer sloping structure has strong adaptability to wind and waves,and has certain shielding effect on waves.The inside vertical structure can be used as wharf to realize mooring and platform operation functions.At present,there are few researches on semi-vertical and semi-sloping breakwaters in the code,and the wave dissipation effect and wave force reduction coefficient of sloping breakwaters are lack of theoretical support.In this paper,combined with engineering examples,a physical model test is carried out to verify,the measured wave data are compared with the calculated values of the wave forces in front of the vertical wall and on the top of the sloping wall in the code,the difference between the conclusions of the two methods and the results of model test is analyzed,and the values of wave force reduction coefficients at different locations are proposed,the structural stability is checked by the measured values of wave force test and some suggestions are given.The research results can provide reference for similar projects.
