| 大跨距漸變四連拱隧道施工力學效應(yīng)數(shù)值模擬研究(49 卷) |
| 英文標題 |
| Numerical simulation study on mechanical effect of tunnel with changeable large span four continuous arch |
| 摘要 |
| 以秦嶺終南山公路隧道2號通風豎井工程風道系統(tǒng)一大跨變截面四聯(lián)拱隧道為工程背景，采用三維有限差分（FLAC3D）對該四聯(lián)拱隧道施工過程進行了三維數(shù)值模擬計算，計算分析了開挖過程中和開挖后的二次應(yīng)力場、變形場變化規(guī)律和塑性區(qū)分布特征，得出了關(guān)鍵施工部位的位移和應(yīng)力分 |
