摘要
在既有隧道旁开挖新的隧道,而不能影响线路的运营,这对新建隧道的施工来说具有相当大的难度,特别是在两隧道线间距很小的情况下,可谓是难上加难。文章简要地介绍了宝成复线须家河隧道在非常困难的条件下,控爆施工过程以及采取的主要技术措施。
It is considerably difficult to build a new tunnel by the existing tunnel side without interfering with the running of railway. In particular, it is more difficult under small distance between two tunnels. This paper briefly introduces the blasting control construction and its main technical measures taken in Xujiahe tunnel on Baoaheng Double -Line Railway under extremely difficult condition, which will be a reference for similar projects.
