摘　　要：目前,我国轨道交通工程建设施工过程中,部分新建线路面临穿越已有线路的问题,已建成地铁线路的运行安全性受新建隧道工程的影响。这是工程建设期间需要关注的核心问题,也是使用隧道抗浮加固技术的主要原因。基于此,本文以我国某地轨道工程项目为例,对其中明挖隧道和地铁交又段的盾构隧道抗浮加固施工进行研究,探讨工程基本状况和使用的工艺原理,并根据工程建设的基本原则,研究盾构隧道抗浮加固施工操作要点。At present,in the construction process of China's rail transit projects,some new lines face the problem of crossing existing lines,and the operational safety of existing subway lines is affected by the construction of new tunnels.This is the core issue that needs to be paid attention to during the construction period,and it is also the main reason for using tunnel anti floating reinforcement technology.Based on this,this article takes a railway engineering project in a certain area of China as an example to study the anti floating reinforcement construction of shield tunnels at the intersection of open cut tunnels and subways.It briefly discusses the basic conditions of the project and the process principles used,and based on the basic principles of engineering construction,studies the key points of anti floating reinforcement construction of shield tunnels.
