The sinking and installation technologies for Honggu Tunnel in Nanchang are introduced. The influencing factors of deviation of tunnel segment and deviation rectification methods are summarized. The horizontal dislocation method and segment tail swing method are adopted for deviation rectification of tunnel segment of Phase 1 of Honggu Tunnel. The construction effect is good. Suggestions are given for axial line control of tunnel segment sinking of Phase 2 of Honggu Tunnel in terms of steel end shell manufacturing accuracy, horizontal flow velocity and segment sinking monitoring accuracy.
