摘要: 采用隧道掘进机(以下简称TBM)是目前城市轨道交通隧道开挖施工的主要方法之一,考虑到TBM自身荷载大,可能对隧道及地铁车站结构造成变形,影响结构稳定性。以重庆轨道交通6号线一期大龙山及冉家坝车站监测实践为例,研究TBM过站的隧道及车站结构变形特征和主要影响因素,提出TBM过站监测方面的见解,从而降低TBM过站安全风险,确保结构安全稳定,为类似工程的变形监测提供一定的参考和借鉴。

Abstract: TBM tunnelling is one of the most popular methods in the excavation of railway tunnels at urban areas. Due to the large load of TBM, the structure stability of the tunnels and Metro stations would be affected a lot. The monitoring opinions of TBM crossing the Metro stations are presented and the deformation characteristics and influencing factors of tunnels and Metro structure when TBM crossing the stations are studied, with the monitoring practice on Dalongshan station and Ranjiaba station of the first phase on No. 6 line of Chongqing railway transit as an example. In the end, the safety risk of TBM crossing the station is lowered and the structure stability is guaranteed. The paper can provide reference for deformation monitoring of the similar projects in the future.
