摘　　要：依据有限元空间分析理论,选取某码头第一结构分段作为分析对象,建立空间模型,在假设的两种工况下分析面板对结构内力的影响。模拟结果表明,高桩梁板码头中码头面板宽度及面板与梁的连接关系是影响内力匀化效果的关键因素;码头面板宽度控制匀化荷载的效果,而厚度对匀化的作用不明显;控制外荷载是水平荷载还是竖向荷载是影响模型选取空间模型还是平面模型的重要条件。因此,在码头设计时,应充分考虑码头面板匀化水平荷载的作用,减小码头结构中关键构件的尺寸,节约成本。Finite element spatial analysis theory is followed to select the first segmental structure of a wharf,and a spatial model is built to analyze the influence of a panel on structure internal force under two working conditions.The simulation results show that the key factors affecting the homogenization of internal force include the width of the panel of beam-slab wharf on piles as well as the connection relation between the panel and beam.The homogenization load is subject to the panel width,while its thickness has insignificant effect.Horizontal or vertical load will influence the final selection of spatial or plane model.Therefore,the homogenization of horizontal load on wharf panel shall be fully considered in the wharf structure design,which can reduce the sizes of key components and construction cost.
