摘要

应用特征函数展开法，研究了作用在二层海洋中立于可渗弹性海床上垂直圆柱的波浪渗流力问题，给出了由表面波和内波分别所引起的渗流压力场的解析解式，由此推导了作用于固立墩柱底部上由波浪渗流压力所导致的浮托力和倾覆力矩算式，并进行了相应的计算。计算结果反应了二层海中渗流波浪力的各种可能变化趋势，说明内波对波浪渗流力可能存在明显影响。

Abstract

The wave seepage forces on vertical circular cylinder resting on porous elastic seabed in two layer ocean has been investigated by applying the eigenfunction expansion approach. The analytical solutions to seepage pressure fields caused by surface wave and inner wave respectively are given and

accordingly

the formulas of the waveinduced lift force and moment caused by the seepage pressure on the bottom of vertical circular cylinder are derived and evaluated. The results reflect possible changes of wave seepage forces on the bottom of vertical circular cylinder in two layer. It is demonstrated that inner wave may have an obvious influence on wave seepage forces.
