Construction method of bridge tower steel-concrete combined section and structure of bridge tower steel-concrete combined section

The invention discloses a construction method of a bridge tower steel-concrete combined section and a structure of the bridge tower steel-concrete combined section, and relates to the field of bridge engineering. The construction method of the bridge tower steel-concrete combined section comprises the following steps that S1, annular reinforcing steel bar pre-embedding operation is carried out through annular reinforcing steel bar hoisting equipment of the bridge tower steel-concrete combined section, and a concrete transition section and a concrete tower column are integrally poured on site; s2, the perforated steel plate shear keys and the stud shear keys are welded to the inner surface of the outer wall steel plate, and then the outer wall steel plate and the lower surface of the perforated pressure-bearing steel plate are welded into a whole; s3, it is ensured that the circumferential steel bars penetrate through holes of the perforated steel plate shear keys, the vertical steel bars penetrate through hol
