在鄂霍次克海（萨哈林岛东南陆架）地形条件下，多分量正压潮汐流产生的非线性内波引起的速度场可用于估算海洋工程结构水下垂直圆柱形部件的动力载荷。侧表面压力强度和速率惯性矩根据直径为 2.5 m、高度为 100 m 的圆柱形桩的 Morison 公式表示，并计算为时间函数。在潮汐泛滥阶段，它们的值分别可达 1.9·105 N 和 10 MN·m。
The velocity field induced by nonlinear internal waves generated by multicomponent barotropic tidal flow over topography for the conditions of the Sea of Okhotsk (South-East shelf of Sakhalin Island) is used to estimate dynamical loads on underwater vertical cylindrical parts of marine engineering structures. The intensity of lateral surface pressure and the rate inertia moment are expressed according to Morison’s formula for a cylidrical pile of 2.5 m diameter and 100 m height and computed as functions of time. They can reach values of 1.9·105 N and 10 MN∙m, respectively, during the flood phase of the tide.
