【摘要】 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。研究了冲击压强沿承台底面的分布,给出了冲击压强随入射波周期、波陡及承台相对净空的变化规律。由于上部承台的加入,下部单桩柱的水动作用力将变化。初步讨论了承台对桩柱受力大小及频率的影响, 并与上部无承台的单桩受力结果进行对比分析。更多还原

【Abstract】 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 slab are measured by pressure transducers and hydrodynamic loads acting on the pile are measured by a four component balance. The influences of wave period,wave steepness, and clearance height of slab on the impact pressures are discussed in detail. In addition, the existence of slab has obviously influenced hydrodynamic loads on pile, which is analyzed preliminarily.更多还原
