G045线赛里木湖至果子沟口段公路改建工程将军沟隧道右线YK582+461～+400段隧道在施工中发生了较大塌方和初期支护变形侵限等事故。论文在分析将军沟隧道变形侵限机理基础上,详细介绍了将军沟隧道初期支护变形段施工处理方案,以及将军沟隧道该段处理变形侵限的临时支护形式、加强支护手段和隧道该段塌方变形段采用的CRD开挖方案。将军沟隧道变形段在论文介绍方案的指导下顺利通过,实践证明了论文方案的可行性,论文介绍了将军沟隧道大变形侵限段的处理技术对同类隧道的施工具有积极的指导和借鉴意义。
G045 Line Reconstruction Project of Sailing Lake to Fruit Mizoguchi Section JK tunnel on the right line YK582 + 461 ~ + 400 tunnels occurred in the construction of a larger landslide and the initial support deformation and other violations. Based on the analysis of the tunnel tunnel deformation intrusion mechanism, this paper introduces in detail the construction treatment scheme of the initial support deformation section of the Junjugou Tunnel and the temporary support form for handling deformation deformation in this section of the Junliangou Tunnel, and strengthens the support measures and tunnels The CRD excavation scheme adopted by this section of landslide deformation. The tunnel section of Jiangjun ditch successfully passed under the guidance of the paper introduction program, and the feasibility of the thesis was proved by practice. The paper introduces that the treatment technology of the tunnel with large deformation in Jun ditch tunnel has positive guidance and reference for the construction of similar tunnels .
