| 超大断面黄土隧道CRD法开挖的三维有限元分析(50 卷) |
| 英文标题 |
| Three-dimensional finite element analysis on excavation of loess tunnel with super-large cross section using CRD(Cross Diaphragm) method |
| 摘要 |
| 进口位于湿陷性砂质黄土中的凤凰岭隧道，开挖面积达170 m2，由于开挖难度巨大，采用了CRD法开挖技术。运用“PLAXIS 3D Tunnel”三维有限元程序，对CRD法的开挖过程进行了模拟，并考虑了降雨对隧道开挖的影响。计算得出了地表沉降和拱顶下沉，与现场实测值进行了对比分析。此 |
