The invention relates to a processing method of stiffening plates in a reinforcing area of a large-diameter tubular column, and belongs to the technical field of processing and manufacturing of building steel structural members. The processing method comprises the following operation steps that firstly, rolling and forming are carried out on the large-diameter tubular column by adopting a plate rolling machine, and welding is carried out on longitudinal seams after rolling and forming; secondly, the surface of a longitudinal weld joint is polished to be flush with a base metal after welding; thirdly, outer ring stiffening plates are welded to the lower end of a variable-cross-section circular pipe, the upper end of a straight-section circular pipe and the position between the variable-cross-section circular pipe and the straight-section circular pipe; fourthly, an end transverse stiffening plate is welded to the middle of the variable-cross-section circular pipe, then transverse stiffening plates and vertical
