The mechanical characteristics and construction technology of center deep ditch in cold region railway tunnel was studied. Using finite element mode,the mechanics characteristic of shallow buried partial stressful tunnel was done. It shows that the center deep ditch increases hori-zontal and vertical deformation of the tunnel structure greatly.
