摘要
孤立子内波在传播过程中所产生的突发性强流对海洋工程、石油钻井平台等会造成严重的破坏。本文引入了Morison的经验方法、模态分离法来估算孤立子内波对小直径圆柱形桩柱作用力。在计算中所保留的模态数目对所得的解有一定的影响 ;所得的解的精度还取决于观测资料的数量 ;
The sudden strong current induced by internal soliton during its propagation can cause severe threat to the ocean engineering and oil drilling platform etc. In this paper, Morison's empirical method and modal separation were introduced to estimate the internal solitons' force on small diameter cylindrical piles. It is shown that the number of the modes retained in the calculation has some effect on the solution, and the precision of the solution also depends on the number of the observational data. The force and torque exerted by internal soliton are much larger than those by surface wave.
