| 摘 要： | 通过开展物理模型试验,进行不规则波作用下不同间距大直径圆筒防波堤的波峰压力分布规律研究,分析了圆筒相对间距、相对水深、波陡等主要影响因素对圆筒波压力的影响规律,并通过波压力试验值与各家理论公式计算值的比较,进行不同间距圆筒波压力的计算方法研究。基于直立墙结构和大尺度孤立墩柱结构波压力公式给出修正系数以及横向衰减函数的拟合公式,用以计算圆筒周身不同位置处的波压力,从而为工程设计和理论研究提供参考。

| Abstract: | The distribution of wave peak pressure of the large diameter cylinder breakwater with different spacings under irregular wave is studied, and the wave pressure influence rule of main factors is analyzed such as relative spacing, relative depth and wave steepness, with the aid of physical model test. Based on the comparison between the wave pressure test and the theoretical values, the calculation method of wave pressure of the cylinder with different spacings is given. The wave pressure calculation formula of the cylinder breakwater is provided with the correction coefficient and the transverse reduction function, on the basis of the theoretical wave pressure formula of the vertical wall structure and large scale isolated pile structure. The method can be served as a reference for engineering design and further theoretical research. |
