摘要
悬浮隧道是一种具有较大的发展前景新型交通结构物,但其施工方法还缺乏系统的研究。文中分析了悬浮隧道管体节段预制和拼装过程中的主要技术难点,针对性提出了管体装配式钢-混组合截面、水下拼接施工定位装置和顶推施工临时锚固装置的概念设计方案,可为悬浮隧道施工方案的制订提供参考。
Submerged floating tunnel(SFT)is a new type of traffic structure with great development prospect.How⁃ever,there is still a lack of systematic research on the construction of the SFT.In this paper,the main technical diffi⁃culties in the prefabrication and assembly of SFT tube was analyzed,and the conceptual design schemes of the as⁃sembly steel-concrete composite section,the installation positioning device for the underwater segment assembly method and the temporary anchorage device for the incremental launching method were put forward,which may pro⁃vide references for the construction scheme of the SFT.
