摘　　要：从三峡库区变动回水区特殊的地形地质及水文条件出发,以寸滩港三期拟建工程为实例,通过对结构形式特点比较、施工方法论述及合理施工水位确定等要素的分析,对架空直立式码头结构进行排架跨度、基桩桩径优化设计,提出了适应于三峡库区变动回水区的大桩径、大跨度架空直立式码头结构形式,比传统的码头结构工程量减少、工程造价降低,并解决了三峡成库后低水位施工期短的难题。此研究成果可为库区码头建设提供良好的技术支持,具有一定的参考价值。From the special terrain geological and hydrological conditions in the fluctuating backwater area of the Three Gorges Reservoir area,taking the proposed third stage project of Cuntan as an example,this paper compares the feature of structural type,analyzes the construction method and determines reasonable construction water level,optimum design of bent span and foundation pile diameter on overhead vertical wharf structure,and proposes a large-diameter-pile and long-span overhead wharf structure pattern adapting to the fluctuating backwater area of the Three Gorges Reservoir area,which can reduce the work amount and construction cost comparing with the traditional ones,and solve the problem that the low water level construction time is short after water storage of the Three Gorges Reservoir.The research results can provide a good technical support and may serve as reference for reservoir wharf construction.
