摘要
隧道进洞是隧道施工中的一个难点,炭质泥岩段隧道进洞更加困难,结合贵州省惠水至罗甸高速公路某隧道进洞施工,提出"两端固结梁"隧道进洞施工方案,成功地解决了炭质泥岩隧道进洞问题。
Combined with a highway tunnel hole construction in Guizhou, this paper put forward tunnel hole construction scheme of "consolidation beams on both ends", which successfully solved the problem of carbonaceous mudstone tunnel hole.
