摘　　要：通过对我国港口现状的分析,对高桩码头上部结构改革状况的研究,提出了适应深水大跨要求的悬链线拱式纵梁码头结构型式。该结构能充分利用拱结构的跨越能力和钢筋混凝土的抗压性能,大幅度增加码头的排架间距,减少水下工程量,进而降低工程造价。与上海港洋山港区三期工程的普通纵梁结构相比,该结构排架间距可增大到28 m,基桩数量和水下施工工程量明显减少,工程造价降低23%。According to a study on China′s current port situation and change of the high-pile and beam-slab quay superstructure,a new type of wharf with catenary arch longitudinal beams,which can accommodate deep water and large span,is brought up in this paper.This new wharf structure can make full use of arch′s overhead crossing and reinforced concrete′s compression resistance,improve the interval between transverse bents greatly,and decrease the underwater construction quantity.So the construction cost will be reduced.Taking the third phase project of Yangshan Deep-water Port as an example,a comparative analysis on the catenary arch longitudinal beams and conventional longitudinal beams is carried out.The result shows that the catenary arch structure can improve the interval between bents up to 28 m,decrease the number of piles and underwater construction quantity,and cut the project cost by 23%.
