钢管板桩结构位移分析

钢管组合板桩结构作为一种新型板桩结构,在大型深水码头中应用在国内尚无工程实例。此种新型结构计算方法尚未成熟,在设计计算中采用规范简化方法无法对结构位移进行全面分析,有必要运用多种数模软件进行计算分析,同时结合施工的步骤,全面分析结构受力,为设计提供技术支撑。结合某20万DWT集装箱深水码头工程,利用Autodesk Robot、PLAXIS、ABAQUS等软件进行计算,得出一致结论:本工程设计施工工序合理,位移可控;大部分位移发生在施工期且位于桩顶,最大水平位移10 cm左右。该设计方法和结论为类似工程设计提供参考。

Analysis of displacement of steel tubular-sheet pile structure

As a new type of sheet pile structure,steel tubular-sheet pile structure has never been applied in large- scale deep water docks in domestic engineering instance.This new structural calculation method is not yet mature and cannot be used in overall analysis on the structural displacement when design calculate in a simplified way.So it is necessary to conduct analysis and calculation by various numerical simulation softwares,and connect to all procedure of the construction to analyze the force.The results can provide technical support for design.Based on the analysis of certain 200 thousand DWT container deep water dock project and calculation by finite element softwares such as Autodesk Robot,PLAXIS and ABAQUS,we obtain the same following conclusions:the displacement is controllable with reasonable construction procedure;most of the displacements occur in construction period and located at the top of the pile,and the maximum horizontal displacement is about 10 cm.The method and conclusions can provide reference to similar engineering design.
