| 中文摘要: |
| 随着交通基础设施建设的迅速发展,采用双侧壁导坑施工软弱围岩段偏压大跨径隧道的工程项目越来越广泛,笔者通过对工程实例的研究,对双侧壁导坑的施工顺序与偏压隧道初期支护变形的相关关系,进行了归纳和总结,以期为以后的工程施工提供参考。 |
| 英文摘要: |
| With the rapid development of traffic infrastructure construction ,double sidewall drift construction is widely used in large-span deflective pressure tunnel to control the soft surrounding rock deformation. Combined with engineering practice, this paper analyses the relation of construction process and initial support deformation of deflective pressure tunnel,which could be refered to the same projects. |
