摘要
在简述底部有、无缝隙浅海底座波浪外力的研究概况后,本文给出了利用区域分割特征函数展开法计算无缝隙浅海底座波浪外力的结果,并与三维势流理论计算的结果及水池模型试验结果进行了比较,其结果表明:上述之区域分割特征函数展开法,对计算柱形浅海底座波浪外力是一种行之有效的简易方法。
Wave forces acting on the offshore structure are of importance from the str-uctural design point of view. In this paper, after reviewing the current investigation on wave forces on the bottom without gap between the structure and sea floor in shallow sea, a method named eigenfunction expression and matching technique is used to calculate wave forces acting on the bottom of cylindrical shape. A comparison is made between the present results and the experimental ones which have been measured at the wave tank of China Ship Scientific Research Center. It may be seen that they agree quite well.A comparison is also made between the results of 3-D boundary integral equation method that has been developed at CSSRC and those of tne matching method. From the comparison, one can conclude that the present method is an effective and very efficient ore.
