| 摘 要： | 以渝黔高速公路二期工程的笔架山隧道为工程背景,采用对现场主体工程施工过程和隧道建成初期的跟踪监测,与三维弹塑性数值模拟相互对照的方法,得出了高速公路隧道施工期间和建成初期的力学行为及变化规律。另外,采用偏于安全的结构—荷载模式对此隧道不同类别的二次衬砌长期安全性进行了计算,得出了各类围岩隧道结构的长期安全性指标的数值大小和横向分布规律。其结论可为隧道设计和施工提供重要参考。 |
| 关 键 词： | 高速公路隧道 现场监控量测 数值模拟 长期安全性 |

| Abstract: | On the basis of Bijiashan Tunnel in 2nd stage project of Yu-Qian Expressway,monitor and 3D numerical simulation are applied to study on structures during construction stage and initial completion stage,and to find mechanical behavior and variation laws of expressway tunnel during construction stage and initial completion stage.In addition,structure-load mode on the safe side is used to compute long-term safety of final linings with different type,and magnitude and transversal distribution of long-term safety index are attained for tunnel structures under different surrounding conditions.The results provide the references for design and construction of tunnel. |
| Keywords: | expressway tunnel in-situ measurement numerical simulation long-term safety |
