摘要
本文给出了安置在海床上大尺度墩桩底面波浪渗流压力的计算方法和一些数值结果。考虑了墩柱直接放置在海床上和放置在埋入海床中抛石基床上两种情况。计算中对内场采用有限元方法,对外场给出了两种处理方法:一是给出了渗流压力外场解;二是建立了一个无限元模式。分析中考虑了海床土壤变形和孔隙水压缩性,讨论了海床土壤变形和孔隙水压缩性以及抛石基床对墩柱底面波浪渗流压力的影响。圆墩柱情况的计算结果与其它文献的解析结果和实验结果吻合良好。
This paper presents the calculation method and some numerical results of wave -induced seepage pressure acting on a gravity Structure resting on porous elastic seabed or a rubble-mound embeded in the seabed. The finite element method is used in the inner domain.in the outeer domain, two calculation methods are given, one is to give an outer domain solution of seepage pressure, the other is to establish an infinite element mode.The deformation of soil skeleton and the compressibility of pore water are taken into account in the calculation and their effect as well as the effect of the rubble-mound on seepage pressure are discussed. The a-greements between our numerical results and Other author's analytical and experimental results for a circular pier are good.
