波流联合作用下深海扬矿管的水平液动力载荷

Horizontal Hydrodynamic Load of the Lifting Pipe in Deep Ocean under the Combination Effect of the Wave and Current

分析了波浪水质点速度和加速度、海流速度、扬矿管直径、海水密度等对扬矿管水平液动力载荷的影响,推导出扬矿管水平液动力载荷的计算公式,并通过计算实例揭示出扬矿管水平液动力载荷与和海洋深度变化的关系。

The paper analyses the effect of the velocity and acceleration of wave particle, the velocity of current, the diameter of lifting pipe and the density of seawater to the horizontal hydrodynamic load of lifting pipe, deduces the formula for calculating the horizontal hydrodynamic load of the lifting pipe, and discloses the relationship be- tween the horizontal hydrodynamic load of the lifting pipe and the alteration of oceanic depth by a calculation example.
