Zusammenfassung:	The invention discloses a tunnel crack reinforcing method. The tunnel crack reinforcing method comprises the following steps that S1, the surface of soil around a crack is cleared to form a to-be-reinforced face, a reinforcement mesh is hung on the to-be-reinforced face, and polymer mortar is poured; S2, crack sealing glue is poured into the crack; and S3, a plurality of steel plates are anchoredin the direction of the crack path at intervals. According to the tunnel crack reinforcing method, the reinforcement mesh is arranged on the to-be-reinforced face, the reinforcement mesh and the tunnel soil form an integral structure, the stress at the tunnel crack can be effectively lowered, and the situation that the crack is further expanded and consequently partial collapse of the soil is caused is prevented; meanwhile, the crack sealing glue is poured into the crack, the steel plates are laid on the surface of the crack, thus the crack is filled, the surface of the crack is also blocked through chemical anchoring
