摘要
为深入认识高桩码头的被动桩形成机理,考虑桩与岸坡相互作用,地基土弹塑性特性,桩土接触界面非线性,通过建立高桩码头与岸坡的共同作用有限元模型,分析其在自重状态下的被动桩特性形成机理,结果表明:在岸坡侧向变形作用下,码头结构产生了显著的附加内力,其影响不容忽视,在高桩码头的设计施工中须予以重点考虑。
In order to study the passive pile mechanism of piled wharf, with consideration of the pile-soil interaction, elasto- plasticity of subsoil and discontinuous interfaces between pile and subsoil, through establishing the piled wharf-bank slope FEM model, we analyzed the passive pile mechanism of under its self-gravity state, and drawn some significant conclusion. The results show that slope deformation results in piled wharf generating remarkable additional internal forces, the impact should not be ignored, which shouht be mainly considered in the design and construction of piled wharfs.
