摘要
计算了在线性波或椭圆余弦波作用下双圆墩柱波浪渗流力，讨论了双墩 柱沿波向串列和并列布置时墩柱上渗流力随墩距的变化．计算中在内域采用 有限元方法，在外域使用了本文给出的外场解．进行了双墩柱波浪渗流压力 测量的模型实验．渗流压力的计算结果与实验结果符合较好．
This paper investigates the seepage pressure in porous elastic seabed underneath two vertical circular cylinders by a finite element method, which is matched with an outer field solution established. The influence of charge of the distance between cylinders on the seepage force of each cylinder is investigated for two-kind incident waves of sine and cnoidal waves and for various arrangements of cylinders. The governing equation for seepage pressure is based on the Biot' s consolidation theory. The wave pressure on seabed is calculated by the water wave potential theory. Experiments measuring seepage pressure at the bottom of cylinders are conducted. The agreement between numerical and experimental results of seepage pressure is satisfatory.
