摘　　要：基于港珠澳岛隧工程沉管建造经验技术总结和再创新,提出并详细介绍了适用于混凝土整体管节平行流水线作业工厂预制方法,且定量地分析了该方法较传统工厂法的优势,其优势在于工期更短、用地更少,且工作量得以优化。随着沉管隧道长度增加,管节数量增多,其优势愈加明显。Based on the experience and technology summary of immersed tunnel construction of HZMB island and tunnel project and its further innovation,we proposed and introduced a paralleled-flow-line-prefabrication factory method for concrete type monolithic element of immersed tunnel,and quantitatively analyzed its advantages as compared to conventional factory method,which lies in shorter construction period,less land occupation and optimized workload.With the increase of the length of immersed tunnel and the number of tube elements,its advantages become more obvious.
