摘　　要：论文基于大量国内外调研和国内现有相关设计标准、规范、研究理论成果的基础上,总结了国内外三明治结构沉管结构设计施工的实践经验。通过大量国外设计施工调研、工艺试验参数论证、可行性检测类型的成套技术咨询,依托港珠澳大桥岛隧工程最终接头施工实例,采用＂引进、吸收、转化、创新＂的思想制订了一套适合最终接头施工的技术方法。Based on a large number of investigations in China and overseas countries as well as related design standards,specifications,and theoretical studies achievements,this paper summarizes the practical experience of design and construction of sandwich structure immersed tube at home and aboard,and through a large number of investigations and studies and verifications of test parameters as well as technical consulting of feasible monitoring types,relying on the example of the final joint construction of the Hong Kong-Zhuhai-Macao Bridge Island Tunnel project,the idea of ＂introduction,absorption,transformation,and innovation＂is used to formulate a set of technical methods suitable for the final joint construction.
