摘　　要：以国内外已建沉管隧道相关施工技术为依托,对常用管节沉放方法进行对比分析。阐述常用管节沉放方法如浮吊法、浮箱沉吊法、升降平台法和抬吊法的施工流程及技术措施,并对4种管节沉放方法的优缺点进行综合比较,给出每种管节沉放方法的适用范围,为沉管隧道管节沉放方法的选择、工艺优化以及新技术研究提供参考依据。According to the immersed tunnel projects built at home and abroad, we summarize the popular sinking methods for immersed tubes. Based on the study about the construction process and technical measures of the popular methods, such as floating crane method, floating box method, SEP method and square barge method, we present the merits and faults, and give the applicability of each sinking method to provide a reference for the method choice, technical optimization and new technology research.
