摘要
在考虑堤顶越浪的情况下,对典型的设有挡浪墙和挡浪板的桩基透空式防波堤进行防浪特性研究。分析不同结构形式对堤后波高及其变化规律的影响;通过测量上部结构所受波浪力,对比防浪墙结构形式对结构受力的影响;并就结构形式对堤后波高和结构受力的影响关系进行研究。结果表明:合理的上部结构设计,可以在满足防浪要求的同时有效减少结构所受波浪力。
The wave attenuation characteristics of typical pertbrated breakwater are researclaed based on practical engineering applying pile foundations and with wave wails and wave boards installed. Wave heights are measured to analyze the influence of structure forms on wave heights and propagation. Wave forces on superstructures are measured to analyze the influence of different forms of wave walls or boards on structure stress. At last, the correlation between wave height and structure stress, which are both influenced by structure forms, is studied. Results show that a reasonable design of superstructure could effectively reduce structure stress while fulfilling the need for wave attenuation.
