| description | The invention discloses a fracture influence tunnel cavity advanced reinforcement method which comprises the following steps: detecting whether a cavity is formed in a to-be-constructed tunnel surrounding rock or not, and if so, arranging a filler in the cavity for supporting the surrounding rock; and a pipe shed is arranged in the tunneling direction of the excavation face of the to-be-constructed tunnel, the extending direction of the pipe shed is the same as the tunneling direction, and the pipe shed is used for supporting the surrounding rock. The method has the advantages that the surrounding rock cavity is disposed in advance, the filler is arranged in the cavity, collapse is prevented, pipe shed instability caused by impact of collapse on the pipe shed after pipe shed supporting is avoided, the construction process is simple, and other buildings cannot be damaged. Grouting liquid is injected into the pipe shed; the loose surrounding rock at the top of the excavation face is cemented; a shell-shaped str |
