摘要
建立二维非线性数值波浪水槽,模拟了规则波条件下破碎立波对直墙建筑物的作用。从直墙上压力分布和各测点的压力过程线等方面与物理模型实验结果进行比较,讨论了破碎立波的作用特点,分析了压力过程线出现马鞍形变化的原因。将破碎立波波浪力与按规范方法和立波理论方法计算的结果进行了比较。通过对计算结果的的分析比较,验证了该数值模型的有效性。
A two-dimensional numerical wave flume is established to study the breaking standing wave action on a vertical-wall structure in the case of regular wave. The calculated pressure distributions, as well as variations of the pressure time histories at points on the surface of the vertical wall, are compared with that of physical model tests. The features of breaking standing wave action were discussed and the reason of the saddle-like variations of the pressure process is analyzed. The calculated wave forces are compared with that of design code and standing wave theory. The efficiency of present numerical model is verified by the analysis and comparison.
