摘　　要：针对目前内河大水位差框架码头结构在设计和计算时没有考虑结构在建造过程中的受力特性,建立三维有限元数学模型,对结构的施工过程进行可视化仿真分析,并与传统采用结构一次成型、一次加载的计算模型进行比较。结果表明:这两种方法对结构的位移差异影响有随结构层数的增加而加大的趋势,而内力除底层前撑外,对其它构件影响不大。设计人员应当考虑施工过程对大水位差框架码头结构的影响。In view that the stress features of the structures during construction is not considered in design and calculation of frame wharf with a great range of stage in inland rivers, 3D FEM model is established to conduct the visualized analysis of the structures＇ construction process. The comparison between this model and that built and loaded at one time indicates that the influence on the displacement difference of structures by the two methods will increase with the increase of stories of structures. As for the internal force, it has little influence on other members despite construction process on the the bottom-story front supports. The designers ought to consider the impact of the structure of frames wharf with a great range of stage.
