Abstract：In the design notion of new Austrian tunnelling method，the processes of monitoring and measurement are important and indispensable in the tunnel construction. The work and the analysis based on it not only correctly reflect the stability of surrounding rock，but also optimize the tunnel lining structure as well. Therefore the dynamic design and informational construction of tunnel can be realized. In order to master the real-time deformation of surrounding rock and the stress characteristics of tunnel lining，the stress and displacement monitoring have been carried out in a super-long tunnel through the construction period. Based on the stress monitoring，the stress of the tunnel lining structure in different rock classifications has been simulated using finite element software. The validity of the simulation has been performed through the displacement monitoring and then the critical loads have been acquired. The results can be used in guaranteeing the safety of projects，optimizing the parameters，guiding the tunnel monitoring in the future design.
