Abstract: A tunnel in the construction process will inevitably cause disturbance to the stability of the rock mass, and further affect the original rock stress state and stability, so the surface settlement, the crest subsidence of the tunnel surrounding rock mass convergence have much restrictive requirements. In order to ensure the safety of tunnel construction, this paper takes Guangxi Ganglingpo double cell tunnel of an expressway tunnel monitoring measurement as the research object and choose the appropriate mathematical methods for the analysis of the monitored data. The results of the analyses can predict the final displacement of the surrounding rock and the ground surface subsidence. The rate of the displacement at the tunnel aprons can be used to determine the stability of stability the surround rock mass and the three-dimensional space-time effect of tunnel excavation.
