| 軟弱圍巖隧道施工數(shù)值模擬分析(51 卷) |
| 英文標(biāo)題 |
| Numerical simulation analysis on construction of soft-rock tunnel |
| 摘要 |
| 以渝宜高速公路某隧道為工程背景，采用理想彈塑性材料本構(gòu)關(guān)系及Drucker\|Prager屈服準(zhǔn)則建立二維有限元模型，對(duì)軟弱圍巖公路隧道開(kāi)挖進(jìn)行了數(shù)值模擬，得到了隧道施工過(guò)程中各階段圍巖的應(yīng)力、應(yīng)變以及隧道支護(hù)結(jié)構(gòu)中的內(nèi)力變化情況，并將數(shù)值模擬結(jié)果與監(jiān)控量測(cè)數(shù)據(jù)進(jìn)行了對(duì) |
