摘要
地铁区间隧道施工中,经常会遇到从明挖基坑中直接进行矿山法隧道进洞的情况,为保证明挖基坑的稳定和矿山法隧道进洞段施工的安全,需要对明暗挖交界处进洞施工技术进行研究。该文以厦门地铁一号线岩车区间为例,采取监测数据进行对比分析,对隧道由明挖转为暗挖时的进洞施工顺序进行了探讨,相关经验可为类似工程提供借鉴。
In the construction of metro tunnels, there is often a case of direct excavation of the tun- nel into the hole. In order to ensure the stability of the foundation pit and the safety of the tunnel con- struction, the paper takes Xiaten Metro Line No. 1 as an example, to analyze the construction sequence of the tunnel by turn open-cut method into subsurface excavation method, and the relevant experience can provide reference for similar oroiects.
