| 標(biāo)題 |
| 超大斷面黃土隧道CRD法開挖的三維有限元分析(50 卷) |
| 英文標(biāo)題 |
| Three-dimensional finite element analysis on excavation of loess tunnel with super-large cross section using CRD(Cross Diaphragm) method |
| 摘要 |
| 進(jìn)口位于濕陷性砂質(zhì)黃土中的鳳凰嶺隧道，開挖面積達(dá)170 m2，由于開挖難度巨大，采用了CRD法開挖技術(shù)。運用“PLAXIS 3D Tunnel”三維有限元程序，對CRD法的開挖過程進(jìn)行了模擬，并考慮了降雨對隧道開挖的影響。計算得出了地表沉降和拱頂下沉，與現(xiàn)場實測值進(jìn)行了對比分析。此 |
