对不同水动力条件下跨海大桥桥墩底板上的竖向力进行了试验研究。实验研究分为规则波和不规则波两部分。作用在板坯上的水动力载荷由六分量天平测量，板底压力由压力传感器测量。结果表明，垂直力模式可分为冲击型和浮力隆起型。针对这两种不同的振型，对竖向水动力的时间序列进行了测量和分析。详细讨论了波高、波周期、板间隙高度对垂向力的影响。
An experimental study has been carried out to investigate the vertical force on a slab of sea-crossing bridge piers in the cases of different hydrodynamic conditions. The experimental study is divided into two parts in terms of regular waves and irregular waves. The hydrodynamic loads acting on the slab are measured by a six component balance and pressures on the bottom of the slab are measured by pressure transducers. It turns out that the vertical force patterns can be considered as impact type and bouyant uplift type. For these two different patterns, time series of the vertical hydrodynamic force are measured and analyzed. The influences of wave height, wave period, clearance height of slab on the vertical force are discussed in detail.
