振荡水柱（OWC）装置提供了一种实用和方便的方式来转换波能发电。波浪荷载是影响坐底式防波堤基础安全的重要设计参数。本研究认为OWC集成到坐底桩结构（OWC桩）。采用三维数值模拟的结果，对OWC桩的波浪荷载进行了研究。看来粘性载荷和横向载荷相对较小。纵、垂向波浪力和倾覆力矩对波浪周期的变化不敏感，但随波高的增加而增加。提出了适用于波浪力和倾覆力矩的尺度，用于估算OWC桩上的波浪荷载。
Oscillating-water-column (OWC) devices provide a practical and convenient way to convert wave energy to electricity. Wave loads on bottom-sitting WECs are important design parameters for their foundation safety. This study considers an OWC integrated into a bottom-sitting pile structure (an OWC pile). Results from three-dimensional numerical simulations are used to examine the wave loads on an OWC pile. It appears that viscous loads and lateral loads are relatively small. Both the inline and vertical wave forces and the resulting overturning moment are not sensitive to the variability in wave period, but increase with wave height. Scales suitable for the wave forces and overturning moment are proposed for estimating wave loads on the OWC pile.
