摘　　要：结合重钢环保搬迁大型散货出口码头建设和重庆寸滩架空直立式集装箱码头的成功尝试,提出一种适用于三峡库区大型散货码头的结构形式,即架空直立墩式散货码头。采用有限元方法建立码头结构的三维有限元模型,通过计算得出码头结构在不同工况下的位移和内力分布特点。研究表明,架空直立墩式码头是三峡库区大水位差、大流速、船舶大型化等条件下散货码头的合理结构形式。In virtue of the relocation and construction of large-scale bulk export wharf of Chongqing Steel Group for environmental protection and the successful attempt in overhead vertical container terminal in Cuntan of Chongqing, a type of structure, i.e. overhead vertical pier-type bulk cargo wharf applicable to large-scale bulk wharf in the Three Gorges reservoir area is proposed. This paper uses finite element method to build a 3D finite element model and derives by calculation the displacement and the distribution characteristics of internal force of the wharf structure at different conditions. The results show that the overhead pier-type wharf is a reasonable type of structure for bulk wharf in the conditions of large water-head, large water velocity and upsizing vessels in the Three Gorges reservoir area.
