| 摘 要： | 结合某城市道路,对大跨隧道双侧壁导坑法施工进行了弹塑性数值模拟,探明了施工过程中国岩深部位移、围岩稳定性,以及衬砌结构的受力特性.研究表明,围岩等级较高,围岩条件差的情况下,采用双侧壁导坑法在技术上是可行的,并且能够很好的控制施工过程中围岩的稳定. |
| 关 键 词： | 大跨隧道 双侧壁导坑法 力学行为 数值模拟 |

| Abstract: | In the light of road of a certain city,the paper conductsthe elastoplastic numerical simulation by double lateral wall heading method for tunnel with long span,verified the displacement of surrounding rock's deep position,the stability of surrounding rock as well as the bearing characteristics of lined structure.Result of research show that the grade of surrounding rock is higher;applying the double wall heading method is feasible under the conditions of poor surrounding rock;moreover the stability of surrounding rock in the process of construction can be controlled well. |
| Keywords: | Tunnel with long span Double lateral wall heading method Mechanical properties Numerical simulation |
