|
摘要
以港珠澳大桥沉管隧道工程为依托,分析了外海超长沉管隧道设计需要解决的关键技术,重点介绍了沉管隧道基础沉降控制技术、多点非一致地震激励下超长沉管隧道设计方法、节段接头构造形式研究及高水压120年设计使用寿命OMEGA止水带研发等需要突破的技术,并阐述了主要研究成果。这些研究成果为我国后续外海超长沉管隧道设计提供技术支撑。
Based on the immersed tunnel project of Hong Kong-Zhuhai-Macao Bridge,four key design technologies of open sea extra-long immersed tunnel are analyzed:foundation settlement control technology of immersed tunnel(IMT),seismic design method of extra-long IMT subjected to non uniform seismic excitations,structure type of IMT segmental joint,and development of OMEGA seal with the designed service life of 120 years.The main research results are summarized which will provide technical supports for the construction of IMT projects in future.
