| 標(biāo)題 |
| 超前地質(zhì)預(yù)報(bào)技術(shù)在西格二線關(guān)角隧道的應(yīng)用(50 卷) |
| 英文標(biāo)題 |
| Application of geological prediction technology to construction of Guanjiao tunnel of Xining-Gormo second line |
| 摘要 |
| 關(guān)角隧道是目前我國(guó)已開工建設(shè)的最長(zhǎng)鐵路隧道，位于青藏高原東北緣，區(qū)內(nèi)斷裂及褶皺均較發(fā)育，地質(zhì)條件復(fù)雜；高地應(yīng)力、巖溶、突涌水是隧道施工中的主要地質(zhì)問題。采取正確的超前地質(zhì)預(yù)報(bào)技術(shù)對(duì)其進(jìn)行超前探測(cè)，提出行之有效的防治措施是保證關(guān)角隧道施工安全的關(guān)鍵。 |
