摘要:
南昌市红谷隧道沉管段全长1 329 m,分为12节管节,是目前国内内河最长的沉管隧道工程,其管节安装的轴线精度控制是工程施工的重点及难点。为保证管节安装精度,同时兼顾经济性、便捷性和可行性,以本工程管节安装为例,对管节安装的主要影响因素进行计算,提出利用现有横调系统对管节安装轴线进行纠偏的方案。理论计算与实测数据对比表明,提出的方案可对管节安装轴线进行有效的纠偏,对其他沉管隧道工程也可起到一定的借鉴作用。

Abstract:
Nanchang Honggu Tunnel is a longest inland river tunnel in China. The immersed section of Honngu Tunnel is 1 329 m long and includes 12 segments. The axial line accuracy of segment installation is the key. The main influencing factors of tunnel segment installation accuracy are calculated, and the axial line deviation rectification of tunnel segment is carried out by using horizontal adjusting system. The comparison between measured data and theoretical calculation results shows that the abovementioned axial line deviation rectification method is effective. The study results can provide reference for similar projects in the future.
Key words: immersed tunnel, segment sinking, segment installation, axial line rectification
