摘　　要：用Rankine源面元法数值计算某内河大方形系数双尾船的浅水下沉量及纵倾,计算得到的船体纵倾值随航速的变化在浅水孤独波出现前与试验结果较一致,而下沉量的计算值则明显小于有关试验值,有关数值处理方法仍须进一步探讨。Numerical calculation of wave-making in shallow water for certain High-Block Ship with Twin- Skeg is carried out by Rankine-Source panel method. The calculated trim varying with the velocity are accordant with the experiment data before the appearance of solitary wave in shallow water while the calculated sinkage is much less than corresponding experiment data.
