浅海结构物波浪力计算及实验研究

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。应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。研究结果表明,应用椭圆余弦波理论和双曲波理论计算理论波压力,然后进行修正,用浸没表面积分法计算的波浪力与实验值相接近。

Wave Force Calculation and Experimental Study for Shallow Offshore Structures

The wave forces acting on a vertical pile in shallow water are calculated in this paper using second order conical wave theory, second order hyperbolic wave theory and second order solitary wave theory. An experimental study is carried out in a wave channel, where the wave parameters, the wave forces and wave pressures are tested. The traditional computing method of calculating wave forces is corrected using the experimental data. A correction formula is suggested. The study indicates that the theoretical wave pressure can be calculated using conical and hyperbolic wave theories and the wave forces are calculated by integration of the corrected pressures around the pile. Compared with the experimental data, this method gives reasonable results.
