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.
