隧道大变形侵限处治技术

Large Deformation and Transgression Treatment Technology of Tunnel

隧道大变形侵限直接影响隧道工程的工期、安全、经济和质量,是隧道施工中必须重视的技术难题。论文结合施工工程,详细阐述了隧道大变形侵限的原因、撤换情况以及侵限处理中最难的换拱处治技术,为解决隧道大变形侵限处治问题提供了技术参考。

Large deformation of the tunnel directly affects the construction period, safety, economy and quality of the tunnel project, which is a technical problem paid attention to in the tunnel construction. Combined with the construction project, this paper expounds the reasons for the large deformation of the tunnel, the replacement and the most difficult technology of changing the arch in the treatment of invasion, which can provide a technical reference for solving the problem of tunnel large deformation invasion.
