Abstract In this paper, a series of experimental data for wave (current)-induced pore-water pressure around a partially embedded monopile is presented. Unlike the previous studies, the combined action of waves and currents is studied. The partially embedded monopile is considered. The variations of pore-water pressures around the monopile in time and space are investigated by wave flume experiments. The experimental results indicate that the hydrodynamic response and the seabed response caused by the combined action of waves and currents are significantly different from those caused by wave load. When the following current is superimposed on the wave, the wave profile on the lateral side, rather than on the front, of the monopile fluctuates first, and the wave trough of the incident wave becomes small and gentle. Moreover, it was found that the amplitudes of pore-water pressures increase, while the attenuation of pore-water pressures slows down under the large wave energy with a large current. It was further found that the existence of a current has a significant effect on the pore-water pressure at z ∕ h = -0.3 on the front side and on the pore-water pressure at z ∕ h = -0.15 on the back side of the monopile. Additionally, the influence of the current on the vertical and horizontal distributions of pore-water pressures is related to the wave height.

在多孔海床中部分嵌入的单桩周围传播的组合波和电流的物理建模

摘要 在本文中，提出了围绕部分嵌入式单桩的波浪（电流）诱发孔隙水压力的一系列实验数据。与以往的研究不同，研究的是波浪和洋流的联合作用。考虑部分嵌入的单桩。通过波槽实验研究了单桩周围孔隙水压力在时间和空间上的变化。实验结果表明，波浪和水流共同作用引起的水动力响应和海床响应与波浪载荷引起的水动力响应和海底响应存在显着差异。当跟随电流叠加在波上时，单桩侧面而不是正面的波型首先波动，入射波的波谷变得小而平缓。而且，发现在大电流大波浪能作用下，孔隙水压力幅值增大，而孔隙水压力衰减减慢。进一步发现，电流的存在对正面 z ∕ h = -0.3 处的孔隙水压力和背面 z ∕ h = -0.15 处的孔隙水压力有显着影响。单桩。此外，水流对孔隙水压力的垂直和水平分布的影响与波高有关。3 在正面和在 z ∕ h = -0.15 处的孔隙水压力在单桩背面。此外，水流对孔隙水压力的垂直和水平分布的影响与波高有关。3 在正面和在 z ∕ h = -0.15 处的孔隙水压力在单桩背面。此外，水流对孔隙水压力的垂直和水平分布的影响与波高有关。
