Accurate adjustment method for tower column stress of cable bent tower

The invention relates to the field of bridge construction, in particular to an accurate adjustment method for tower column stress of cable bent tower. The method comprises the following steps: acquiring a target jacking force P of a cross bracing, a target stress sigma of the bottom end of a tower column and a target transverse deviation f of the tower column; acquiring a stress threshold value and a transverse deviation threshold value according to sigma and f; determining the planned jacking times n and the set jacking force of each time of transverse support jacking, wherein the set jacking force meets the condition that the set jacking force of the ith jacking is the sum of the incremental jacking force distributed by the ith jacking and the set jacking force of the (i-1) th jacking; jacking the tower column for the first time; acquiring the actual stress sigma actual of the bottom end of the tower column and the actual transverse deviation f actual of the tower column; judging whether the actual sigma ex
