摘　　要：结合连云港港徐圩港区的地质特点,提出一种将驳岸和码头结构结合的新型框筒式码头结构形式,并建立相应的数值模型,分析框筒式结构的变形和稳定,得出新型框筒码头结构的稳定性能够满足施工期和使用期变形稳定要求;框筒结构的水平位移主要在施工期完成,使用期水平变形在10 cm以内,而且前板桩墙和桩基共同变位,相对位移差在毫米量级上,不会影响上面门机作业。Combined with the geological features of Xuwei Port in Lianyungang Port, we proposed a new frame drum wharf structure type by combining revetment and wharf structure, and established its numerical model, analyzed its deformation and stability. The results are obtained that the stability of new frame drum wharf structure can meet the deformation stability require- ment in construction and applying period, the horizontal displacement of frame drum structure is mainly complete in construc- tion period, the applying horizontal displacement is within 10 cm, the sheet pile wall and pile foundation are together deformed, the relative displacement difference is on the order of millimeters, the unloaders operation will not be affected.
