| 鉴于《港口与航道水文规范》(JTS145—2015)中缺少扭王字块体斜坡堤越浪量的计算方法，因此开展相关的试验研究对规范发展和工程设计具有重要意义。在基于FLUENT软件的数值模型中，通常采用多孔介质区中的系数C来模拟斜坡上扭王字块体的消浪作用，而确定每种工况系数C的取值是实现数值模拟斜坡堤越浪量的关键。借助物模试验率定出所有工况的系数C，通过单一变量分析，发现C值随波陡、相对水深、相对坡肩宽度及相对块体尺寸的增大而增大，随相对堤顶超高及相对胸墙高度的增大而减小，综合以上影响因素，得出不同坡度下系数C的计算关系式。研究成果不仅丰富了规范内容，还为相关的工程设计提供了参考。 |

| In view of the lack of calculation methods for the overtopping of sloping breakwaters with accropode armor blocks in the Hydrological Code for Ports and Channels(JTS145—2015), it is of great significance to carry out relevant experimental research for the development of code and engineering design. In the numerical model based on the FLUENT software, the coefficient C of the porous media area is usually used to simulate the wave-eliminating effect of the accropode armor blocks, and how to determine the value of the coefficient C for each working condition is the key to numerically simulating the overtopping of sloping breakwaters. The coefficient C of all working conditions is calibrated by the physical model test. Through single variable analysis, it is found that the C increases with the increase of wave steepness, relative depth of water, relative width of shoulder and relative size of block, and decreases with the increase of relative superelevation of embankment top and relative height of parapet. Based on the above influence factors, the calculating formula of inertial resistance coefficients under different slopes are given. The research results not only enrich the content of the code, but also provide a reference for related engineering design. |
