摘要
结合目前的隧道工程施工情况,对地铁隧道工程施工的相关问题进行了探讨。简单概述了隧道开挖在经过基覆分界线情况下隧道的超前探测、超前支护及开挖工法的选择,总结了隧道开挖经过基覆分界地段时施工的注意事项。在隧道施工过程中遇到的地质问题不尽相同,在施工中要区别不同情况,针对具体问题采取相应处置措施,把不良地质情况给施工带来的损失降到最低。
Combined with the current tunnel construction, the construction of the subway tunnel related issues are discussed. The paper briefly describes selection of advanced detection, advanced support and excavation method under the condition of passing base covering boundary line during tunnel excavation, and the construction precautions of tunnel excavation when passing through the boundary section are summarized. Geological problems encountered in the tunnel construction process is not the same, to distinguish between different situations in the construction, appropriate measures are taken to deal with specific problems, to minimize the losses caused by adverse geological conditions to the construction.
