摘要 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
