The invention discloses a steel rail symmetrical full-length fluctuation control method capable of improving steel rail symmetrical full-length control precision. The method comprises obtaining the distribution length l of the symmetrical full-length fluctuation abnormal part on the steel rail and the symmetrical fluctuation mean deviation q according to the symmetry f detection curve under the normal steel rail rolling condition, and determining the roller displacement compensation value Q; allocating the roller displacement compensation value Q to each compensation pass, with the displaceable roller of a universal rolling mill as compensation roller, to make the roller displacement compensation amount Qn of a single compensation pass satisfy |Qn|<=3.5mm, determining a to-be-compensated length L, adjusting the displacement value X=x+Qn of the compensation roller on the to-be-compensated length L, and allowing the displacement value X of the compensation roller to restore to the normal displacement value x du
