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.
