Concentrated charge structure for reducing tunnel disturbance and blasting method

The invention belongs to the technical field of blasting, and particularly discloses a shaped charge structure for reducing tunnel disturbance and a blasting method. The shaped charge structure comprises a blasting tube, a connecting piece, a reinforced charge structure and an end socket, the blasting pipe is filled with explosives, a V-shaped groove is formed in the blasting pipe in the length direction of a pipe body of the blasting pipe, and a matched V-shaped liner is attached to the surface of the V-shaped groove. The connecting pieces are arranged on the blasting pipes in a sleeving mode and used for connecting and fixing the two adjacent blasting pipes. The reinforced charging structure is filled with explosives, and the reinforced charging structure is detachably communicated with the front end of the blasting tube; and the sealing head is detachably connected with the rear end of the blasting tube. The shaped charge structure is simple in overall structure, flexible, simple and rapid in field assembl
