Considering the rigid body displacement and bending deformation of the single-fulcrum pile anchor support structure, the horizontal displacement calculation method of the anchor point and the top of the supporting pile is established. By analyzing the effect of various influencing factors of horizontal displacement on displacement, it is pointed out that the downward shift of the bolt position will increase the tensile force of the bolt and increase its reinforcement, but the horizontal displacement deformation of the pile top after the anchor tension and anchoring can be reduced.
