【摘要】 本文通过模型试验研究了不规则波与均匀流共同作用于小尺度单桩的水动力特征。文中比较了不同工况下直桩与斜桩的受力特性。在频域内采用相关函数法进行了谱分析与互谱分析,得到波面谱与波力谱的相关关系,并给出波向力与波面相位差的变化规律。更多还原

【Abstract】 An experimental study on hydrodynamic loads on a single pile under combination of irregular waves and currents is presented in the paper. The forces are measured by a four component balance. The characteristics of the measured forces on a single vertical pile and inclined pile are compared and discussed. The time series of the measured forces and surface elevation are analyzed in frequency domain using spectral method. It turns out that the phase differences between the surface elevation and the inline force would changes with ambient current.更多还原
