摘要
应用椭圆余弦波理论、双曲波理论及孤立波理论对作用于浅海海洋结构物的波浪力进行了计算 ,并在造波水槽中进行了波浪力及波压力实验研究。运用实验结果对传统的计算方法进行了修正 ,提出了静水面以上波压力的修正公式。研究表明 ,应用椭圆余弦波理论和双曲波理论计算理论波压力并对其进行修正 ,再将积分上限取为瞬时波面 ,积分后得出的波浪力与实验结果很接近。
The wave force acting on a vertical pile in shallow sea water is calculated by using second order conidal wave theory, second order hyperbolic wave theory and second order solitary wave theory. An experimental study on wave parameters, wave forces and wave pressures are carried out in a wave channel. Based on the experimental data,the traditional computing method of wave force is corrected, and a correction formula is suggested. The theoretical wave pressure can be calculated by means of conidal and hyperbolic wave theories, and the wave forces can be calculated by integral of the corrected pressures around the pile with the instantaneous wave surface as the upper limit. Compared with the experimental data, this method gives the reasonable results.
