The invention discloses a construction method for reducing blasting vibration of a structure close to an urban tunnel. The method comprises the following steps of a, during construction, moving cutting holes downwards to be away from an upper protected structure, arranging double-layer small guide pipes within the range of 4 m in front of and behind an underneath pass section, performing advance support, enabling the length of the small guide pipes to be 4 m, enabling the distance between every two adjacent small guide pipes to be 30 cm, performing construction once every other arch frame, driving locking foot anchor pipes strictly according to the designed depth, adding the locking foot anchor pipes at the arch waist, and effectively welding L-shaped ribs and locking feet; b, dividing anexcavation area at the upper part of the tunnel into a first area and a second area, firstly slotting a hole in the first area at the middle lower part of the step, arranging a blast hole and an electronic detonator detonating line, and carrying out blasting excavation of the first area with the excavation process of 0.5m to 1m to form a pilot tunnel so as to provide a complete free surface for other blast holes; and c, after the construction passes through the adjacent structure, arranging a second-area cutting hole, arranging a blast hole and an electronic detonator detonating line, carryingout blasting excavation of the second area, and finally expanding excavation to a designed contour line.
