摘　　要：整体卸荷式承台板桩接岸结构作为一种新型接岸,目前尚无明确的计算方法及力学特性分析,研究该结构的桩基内力分布,优化结构设计,具有一定的工程应用价值。以沿海某重件码头为例,利用水运工程结构CAD集成软件计算设计方案,并进一步研究不同桩径及纵向桩距下的前后排桩受力特征及经济性。分析表明后排桩基桩径的增大对前排桩墙的压桩力及弯矩影响较小,后排桩基压桩力及弯矩均呈现不同程度地大幅增加,桩基水平位移逐渐减小;从桩基础的经济性比选上,更推荐大桩径方案。今后尚需进一步深化桩土作用分析及上部结构内力分析,使该型结构设计更趋合理。The shore-approach sheet pile structure under integral load-relieving pile cap is a new shore-approach structure requires an available calculation method and the analysis of its mechanical properties.The study on the internal force distribution of the pile foundation and the improvement of structure design is worthy of engineering application,Based on a coastal heavy-piece wharf,an integrated CAD software was used to make a design plan,further study the stress characteristics and economy of the front and rear row piles under different pile diameters and longitudinal pile spacing.The results showed that the increase in the diameter of the rear-row piles had little impact on the bending moment of and the pressure acting on the front-row pile wall,significantly increased the bending moment of and the pressure on the rear-row pile foundation,and gradually reduced the horizontal displacement of pile foundation.In terms of the cost of pile foundation,large pile-diameter plan was recommended.It is necessary to carry out in-depth analysis of pile-soil interaction and the internal forces of upper structure in order to produce a more reasonable structure in the future.
