考虑桩上相互作用高桩码头单桩地震反应

本文以唐山地震时天津地区港口高桩码头实际震害为背景，采用Novak模型，研究桩土动力相互作用对码头单桩地震反应的影响；采用Poulos差分法，考虑桩上静力相互作用，研究在地震引起的岸坡永久变形作用下，码头单桩的地震反应；综合考虑桩上动、静力相互作用，研究单桩地震反应的各影响因素，分析桩的不同破坏形式，对高枕码头抗震提出建议。

Taking the real disasters of high level-piled wharf in Tianjin port area during the earthquake occured inTangshan as a background and using Novak model, this paper studies the effects of dynamic interaction of pilesoil on the earthquake response of a single pile, and the earthquake response of a single pile of the wharf underthe innuence of Permanent deformation of the slope caused by earthquake by use of Poulos difference method,considering the static interaction of pile-soil, synthetically consideres the dynamic and static interaction of pilesoil, discusses the various effect factors of a single pile to earthquake response, analyzes the different datnageshape of piles and finally gives some suggestions to the earthquake resistance of high level-piled wharf earthquake disaster
