| 中文摘要: |
| 本文分析了破碎波对桩柱作用力的机制，认为破碎波在静水面以上对桩柱的冲击力和静水面以下的绕流力的机制是统一的。在计算冲击力时，水的压缩性可略去；气垫效应对曲率半径小的桩柱不显著；用现今开发的破碎波流场的计算结果，可简单地用动量原理估算破碎波对桩柱的冲击荷载。 |
| 英文摘要: |
| The mechanism of broken wave force acting on a cylinderi cal pile is investigated.It is found that the impact force of broken wave above the still water surface is consistent with the force of the flow around the pile beneath the surface.The compressibility of water can be neglected during the calculation of impact force since the air cushion effect is not remarkable for piles with small radius.The impact loads on the cylinder pile can be simply estimated according to the momentum principle. |
