本文基于改进后的Morison方程和线性理论分析了作用于水平桩柱上的波流力,文中提出了适用于波流场中水平圆柱上的重新定义KC数(KC_2),实验表明桩的受力系数C_D及C_M与KC_2有良好的相关性,同时证明水流速度对二系数也有所影响,分析表明,规则波的成果可用于在时域中计算不规则波时的波流力,无论是力谱或力的统计分析值均与试验结果吻合良好。本文方法可供实用参考。
In this paper, based on the modified Morison equation and linear theory, the wave force acting on horizontal piles is analyzed. The KC number (KC_2) which is suitable for horizontal cylinder in wave field is proposed. The experiment shows that the stress coefficient C_D and C_M have a good correlation with KC_2. At the same time, it is also proved that the water velocity has an influence on the two coefficients. The results show that the results of the regular wave can be used to calculate the wave power of the irregular wave in the time domain, Statistical analysis of force values are in good agreement with the experimental results. This method can be used for practical reference.
