| 淺埋暗挖黃土隧道施工過程數(shù)值模擬分析(50 卷) |
| 英文標(biāo)題 |
| Numerical simulation analysis of construction process of loess tunnel by NATM (New Austrian Tunnelling Method) |
| 摘要 |
| 采用有限元數(shù)值分析方法對新寶塔山隧道淺埋段施工過程進(jìn)行模擬，得到開挖過程中每一步圍巖的位移場、應(yīng)力場、塑性區(qū)的變化以及支護(hù)結(jié)構(gòu)的內(nèi)力。通過對計算結(jié)果的分析對隧道施工過程中圍巖的狀態(tài)進(jìn)行預(yù)測，進(jìn)而指導(dǎo)施工方案、支護(hù)方法、開挖順序的確定，同時通過對支護(hù)結(jié)構(gòu)內(nèi) |
