The invention belongs to the technical field of tunnel construction, and particularly relates to a tunnel arch frame structure and process for reinforcing a soft soil layer by driving locking feet inadvance. According to the scheme that ground advanced locking foot guide pipes are driven on the ground in advance, and middle and lower step locking foot guide pipes are driven in an upper step holein advance, the time of locking foot construction is saved, the time of soil exposure after each step of excavation is shortened, and the anti-sedimentation capacity of a steel arch frame connected with the tunnel arch frame structure is improved.
