| 標(biāo)題 |
| 地鐵淺埋暗挖施工地層變形規(guī)律的研究(51卷) |
| 英文標(biāo)題 |
| Study on ground deformation regularity during driving metro tunnel by NATM (New Austrian Tunnlling Method) |
| 摘要 |
| 結(jié)合深圳地鐵5號(hào)線靈芝—洪浪站區(qū)間暗挖地鐵隧道工程的復(fù)雜地質(zhì)條件及施工條件，通過對(duì)大量地層變形實(shí)測(cè)數(shù)據(jù)的分析，深入研究復(fù)雜地質(zhì)條件下地層沉降變形的規(guī)律。研究結(jié)果表明，隧道開挖后，增大支護(hù)剛度并及時(shí)封閉成環(huán)，可以有效控制地層變形，滿足了施工允許的沉降要求，可為類似工程提供相關(guān)的技術(shù)參考資料。 |
