阳江港某码头升级改造方案简析

Analysis on the Upgrading and Reconstruction Plan of a Terminal in Yangjiang Port

阳江港某已有码头由于泊位等级低、使用年限长、结构薄弱等原因,难以满足货物运输需要。结合工程实际案例,探讨老码头结构加固改造设计方案。基于现有码头结构及港口规划提出2组改造方案并进行比较:维持既有岸线不变,拆除部分码头结构并新建靠船墩的20000 GT方案;在现有码头结构前方新建作业平台、靠船墩,并增建系缆墩的50000 GT方案。改造后码头泊位等级及通过能力均有所提升,分析两方案各自存在的优劣性,为类似工程实施提供参考。

Due to the low tonnage of berth,long service life and weak structure,it is difficult to meet the needs of cargo transportation for an existing terminal in Yangjiang Port.Combined with an actual case,reinforcing and renovation option of an old wharf is discussed.Based on the existing wharf structure and port plan,2 groups of reconstruction schemes are put forward and compared:20000 GT scheme,which maintains the existing shoreline unchanged,demolishes part of the wharf structure and builds new breasting dolphins;50000 GT scheme,builds new operating platform and breasting dolphins in front of the existing wharf structure,and builds additional mooring piers.Berth tonnage and capacity have been significantly improved after the upgrade.The advantages and disadvantages of the two groups are analyzed to provide a reference for similar project implementation.
