| 松散巖層偏壓大斷面隧道進(jìn)洞關(guān)鍵技術(shù)研究(51 卷) |
| 英文標(biāo)題 |
| Key technologies study on approach to entrance of large profile tunnel in loose rock with biased load |
| 摘要 |
| 進(jìn)洞施工是隧道工程建設(shè)的關(guān)鍵節(jié)點(diǎn)之一，控制不當(dāng)容易引發(fā)山體滑動(dòng)或坍塌現(xiàn)象，從而影響工程質(zhì)量和施工進(jìn)度。廣州繞城公路東段龍頭山隧道斷面尺寸大，右線進(jìn)口段巖層破碎且存在顯著偏壓現(xiàn)象，結(jié)合現(xiàn)場(chǎng)實(shí)際情況，采取了地表注漿、超長大管棚和CRD開挖相結(jié)合的綜合施工技術(shù)，實(shí) |
