连云港徐圩港区码头及驳岸结构选型

Wharf and bulkhead structure selection of Xuwei harbor district in Lianyungang port

  • 摘要: 通过对连云港徐圩港区驳岸结构选型的研究,讨论影响驳岸结构型式的主要因素。对比爆破挤淤堤、全清淤抛石堤、塑料排水板+砂被抛石斜坡堤和桶式基础结构堤等4种驳岸结构的特点、适用条件、对应码头的结构形式和主要经济技术指标,认为桶式基础结构组合高桩梁板结构方案最适宜徐圩港区的建造发展,而且该方案在资源节约和保证投资效益等方面也有优势。为实现工程综合投资成本最低、效益最大化的目标,基于可行的驳岸结构,比较了与斜坡堤和直立堤分别对应的3种码头结构形式,结果表明,满堂码头桶式基础方案投资效益最优。研究结果可供淤泥质海岸挖入式港区的驳岸结构选型借鉴参考,为浅水深用海域的水工结构设计提供新视角。

     

    Abstract: Based on studies of the bulkhead structure selection for Xuwei port area of Lianyungang harbor, the main factors affecting bulkhead structure types are discussed in this paper. Comparing basic characteristics, applicable conditions, structure types corresponding to the wharf and the main economic and technologic indicators of four kinds of the bulkhead structures such as the blasting compacted breakwater, the full dredging riprap breakwater, the plastic drainage board + sand bedding with riprap sloping breakwater and the bucket based structure breakwater, it is found that the bucket based infrastructure in combination with the open type wharf with standing piles is most suitable for construction and development of the Xuwei port area, and this structure type has the advantage in resources saving and guarantee of investment benefits. Based on the available bulkhead structure, three kinds of wharf structure forms respectively corresponding to the sloping and vertical wall breakwaters have been analyzed and compared in order to reach the goal of the lowest cost and the maximum efficiency. The analysis results show that the bucket based structure breakwater is the most optimal structure. These research findings can be used as references in selecting the bulkhead structure types for the dredged port area situated at the muddy coast, thus providing a new perspective for the design of harbor structures placed at shallow sea waters planned as deep port areas.
