【摘要】 按莫里逊方程计算孤立桩柱上的波浪力时，因其速度力是非线性的，当它需要考 虑时，难于用谱法确切地考虑不规则波浪的动力作用。为克服此种困难，本文介绍了 一种比较实用有效的计算方法──波浪数值模拟法。同时探讨了概率分布法对这种情 况的应用，并通过四个不同桩径的算例，对各种计算方法进行了分析比较。更多还原

【Abstract】 It is difficult to consider the exact dynamic effect of irregular waves on an isolated pile by spectral method if the drag force has to be taken into co- sideration, because the drag force is nonlinear according to Morison’s Equa- tion. In order to overcome this difficulty, a more practical and effective method of wave simulation is introduccd in this paper. The characteristic of the wave forces obtained through simulation is analysed and discussed. Moreover,the application of the method of probability distribution for this case is also discussed.the four methods of computation are analysed and com- pared by means of four illustrative examples having different pile diameters.更多还原
