Abstract
With the fast development of scientific technology and city economy construction, Mining method adopted for shallow underground works, have being applied in the construction of underground passages at present. With typical Wenzhou underground passages embedded in silt and built by shallow mining excavation as the project background,3-D stress and deformation characteristics of a passage in the city center was analyzed by means of Finite Difference software FLAC3D, compared with field monitoring data of the underground street passage near the Second Affiliated Hospital of Wenzhou Medical College. Much important engineering information was obtained, such as the displacement deformation and stress nephogram of the passage, which can be referred for the construction of the similar underground projects in soft soil areas in future to make the projects more reasonable, safe and economical.
