摘　　要：结合连云港赣榆港区4~6号泊位码头方案设计和工程地质勘察报告,探讨沉箱码头抛石基床顶高程的影响因素,提出结合材料来源、工程建设费用、施工难易程度、远期发展等综合因素确定抛石基床顶高程,在保证有效持力层深度的前提下,通过减小设计规范计算取值,来降低抛石基床顶高程,减小抛石基床厚度,从而避免材料来源紧张导致的施工延期风险,降低工程造价和施工难度,提高施工质量,为远期发展预留充足空间,为以后类似工程建设提供借鉴。Based on the design and engineering geological investigation report of a caisson wharf in Ganyu Harbor of Lianyungang Port,the research discusses the influence on rubble base top elevation.A method for determinaion of rubble base top elevation is proposed by all aspects of material source,engineering cost,construction difficlty,long-term development,under the premise of ensuring effective depth of bearing stratum,reduce the rubble base top elevation and reduce the thickness of rubble base by reducing the value calculated in the design specification,so as to avoid the risk of the construction delay caused by the shortage of material sources,reduce the construction cost and the construction difficulty,improve the construction quality,reserve enough space for the long-term development,providing reference to the similar engineering project.
