墩柱波浪力试验研究

LABORATORY STUDIES ON WAVE FORCES ON A CYLINDER

通过小尺度以惯性力为主的墩柱波浪力的系统试验,分析非线性效应对桩柱波浪力惯性分量的影响,讨论Stokes波和椭圆余弦波等非线性波浪理论计算桩柱波浪力的适用范围,并就应用线性波浪理论计算非线性条件下的桩柱波浪力提出修正方法。

A series of experiments on wave forces on a cylinder have been carried out when inertia component is dominant for a small size cylinder. By comparing the results of the measured wave forces with calculated results from Airy, Stokes and cnoidal wave theories, the non-linear effect on the inertia component of the wave forces on a cylinder and the fit ranges for different wave theories are analysed. A revision is also suggested for using linear wave theory to calculate wave forces under the non-linear condition.
