摘要
在地面道路与地下隧道的交通接线工程中,往往采用大开挖施作暗埋段结构,这就给地面带来了很大的环境影响,地面出入式盾构法隧道施工技术(GPST)成为解决这种矛盾的有效途径。文章以该技术的示范工程为背景,着重阐述了隧道结构变形因素分析及理论计算以及管片稳定装置、同步注浆控制以及提高隧道接头刚度等隧道变形控制技术。GPST工法的提出拓展了盾构法隧道的应用范围,为隧道线路规划设计提供了一种新的思路。
The cut-and-cover method is normally used in the construction of works connecting surface roads and underground tunnels, which causes great environmental impacts to the ground. Ground Penetrating Shield Technology （GPST） is an effective way to solve this problem. Based on an experimental project, this paper demonstrates shield tunnel deformation control techniques, such as segment stabilization, synchronous grout control, and improvement of joint stiffness, by analyzing and calculating the influential factors of tunnel deformation. This extends the application of shield tunnelling and provides new ideas for tunnel planning and designing.
