The invention discloses a method for judging the strength of a transverse anchor plate of a steam turbine, relates to a method for judging the strength of an anchor plate, and aims to solve the problem that the steam turbine expands axially from a cylinder dead point through a push-pull structure. In order to solve the problem of danger caused by unbalanced friction force in the expansion and contraction process of a steam turbine, the method is implemented according to the following steps that the transverse load P of an anchoring plate is calculated, the vertical load comprises the gravity load of a part, and the gravity load of the part refers to the load of the anchored static part in the vertical direction; load distribution between the anchor plate and the connecting piece is triangular, a point load is arranged at the 1/3 position of the contact length of an acting surface, the 13h position is the acting point of the load P, it is judged that the stresses of the 0 point, the 1 point and the 2 point all
