摘要
本文对规则波作用于承台及单桩的水动力特性进行了试验研究。承台底面的压强及桩柱的水动力荷载分别采用压力传感器、四分力天平量测。主要研究了冲击压强沿承台底面的分布,给出了冲击压强随承台相对净空及相对长度的变化规律。由于上部承台的加入,下部单桩的水动作用力将变化。讨论了承台对桩柱受力的影响,并与上部无承台的单桩受力结果进行对比分析。
An experimental study has been carried out to investigate impact pressures on a slab and a vertical pile due to regular waves. The pressures on the bottom of the slab are measured by pressure transducers and the hydrodynamic loads acting on the pile are measured by a four-component balance. The influences of relative clearance height and relative length of the slab on the impact pressures are discussed in detail. On the other hand, the hydrodynamic force exerting on the single pile is compared between the cases with and without the effect of the slab .
