摘要
根据港珠澳大桥沉管隧道精确贯通的需要,提出了集“设计、预控、拟合、调整”的沉管安装线形控制管理技术,利用AutoCAD、EXCEL软件编制了较系统的程序和计算公式,通过模拟安装评估已知因素对沉管隧道线形的影响,可以快速、准确制定隧道线形调控目标,使沉管隧道线形整体平稳受控,最终实现隧道全线精确的贯通。
According to the need of accurate connection of the immersed tube tunnel of Hongkong-Zhuhai-Macao Bridge,we put forward the line control management technology of immersed tube installation,which integrates"design,pre control,fitting and adjustment",used AutoCAD and EXCEL software to compile a systematic program and calculation formula,and evaluated the influence of the known factors on the line shape of the immersed tube tunnel through the simulated installation.Tunnel linear control objectives can be formulated quickly and accurately,so that the overall alignment of immersed tube tunnel will be controlled smoothly and eventually,and the tunnel can be accurately connected throughout the tunnel.
