| 大管棚超前支護環(huán)形開挖預(yù)留核心土三臺階隧道施工方法(49 卷) |
| 英文標題 |
| Tunnel construction method of arc-shaped excavation and remained earth core and three benches with large-cross-section pipe shed forepoling |
| 摘要 |
| 以天馬山隧道V級(偏弱)圍巖施工為例，通過方案比選，提出了大管棚超前支護V級(偏弱)圍巖，環(huán)形開挖預(yù)留核心土三臺階工法施工技術(shù)。經(jīng)過論證，此方案安全可行，節(jié)省投資，進度加快，可為今后類似隧道的施工提供有益借鑒。 |
