| 摘 要： | 通过系列模型试验，对波浪作用下墩柱周围局部冲刷地形及其形成机理进行了分析，认为最大冲刷深度发生在墩柱前方，与防波堤前冲淤形态类似，分为细沙型和粗沙型。在对各影响因子分析基础上，提出墩柱周围最大冲刷深度计算公式，试验资料表明，该公式与试验值有着良好的一致性。

| Abstract: | Model tests are performed with regular waves in which the effect of wave height, wave period, water depth, sediment and cylinder diameter is evaluated the mechanism of wave induced scour around a large-scale cylinder is studied. The Maximum scour depth occurs in front of the cylinder, and the scour pattern in front of the cylinder can be divided into fine sand type and thick sand type. An empirical formula of the maximum local scour is obtained. |
