为满足加纳特马新集装箱码头防波堤工程设计的需要,进行了波浪断面物理模型试验,对防波堤护面稳定性及堤后波高开展试验研究.结果表明:原设计方案防波堤不能满足稳定要求,对断面进行了优化试验,结合抬高堤顶块石高程和减小堤后斜坡坡度2种方式可有效增加堤后斜坡护面块石稳定性.波浪断面试验中将斜向入射波浪概化成正向入射波浪使得实验结果偏安全,没有条件开展波浪整体物理模型的时候,可以采用对波高进行折减的方法考虑斜向入射的影响.
In order to meet the needs of the engineering design of the new container terminal breakwater at Ghana's Tema Port,a wave cross-section physical model experiment was conducted to study the stability of the breakwater's armor and the wave height behind the breakwater.The results show that the original design of the breakwater could not meet the stability requirements,and thus an optimization experiment was carried out on the cross-section.By increasing the height of the top of the breakwater and decreasing the slope of the back slope,the stability of the armor blocks on the back slope could be effectively increased.During the wave profile experiment,oblique incident waves were generalized as normal incident waves,resulting in a conservative experimental result.When it is not possible to carry out a complete physical model of the waves,the effect of oblique incident waves can be considered by reducing the wave height.
