Abstract: In this paper, the ｓｏｕｒｃｅ of Mei Yuan tunnel and Ya Yu tunnel as the engineering background, in-troducing the construction monitoring of buried section selection, monitoring measurement equipment and in the tunnel construction process, real-time monitoring of the tunnel surrounding rock deformation on the stress of the supporting structure of reasonable monitoring. The monitoring data obtained, according to the statistical comparison of the construction of the surrounding rock deformation and lining stress are analyzed in detail, so wo can draw a series of suggestions to guide the construction and get out a guiding role in the construction of similar projects later.

Keywords: surrounding rock deformation; force analysis; tunnel monitoring
