土压盾构施工对邻近平行隧道的影响研究

Study on the Influence of Shield Construction on Adjacent Parallel Tunnels

地面交通的拥堵使得地铁的发展显得尤为重要,城市地铁通过利用地下空间有效缓解了地面交通拥堵。盾构法是目前城市地铁开挖常用的施工手段,地铁往往会设计成为往返线,在施工的过程中修建2条独立的隧道。双线平行隧道往往会采取先后施工的方法来减小对周边环境产生的扰动,而后挖的隧道不可避免地会对先挖的隧道产生影响。为此,论文针对城市地铁盾构在施工过程中对平行隧道的影响以及主要的控制措施进行分析,以供参考。

The congestion of ground transportation makes the development of subways particularly important, urban subways effectively alleviate ground transportation ?traffic jam by using underground space. Shield tunneling is currently a common construction method for urban subway excavation, subways are often designed as round-trip lines during construction two independent tunnels were built. Two-line parallel tunnels often adopt sequential excavation methods to reduce the disturbance of the surrounding environment, and the tunnels dug later will inevitably affect the tunnels dug first. To this end, this article focuses on the analysis of the impact of urban subway shields on parallel tunnels during the construction process and the main control measures, for reference.
