The invention discloses a pre-stressed anchor rod supporting analysis method and device based on surrounding rock deformation control, and relates to the technical field of tunnel engineering supporting structure design, and the method comprises the steps that first surrounding rock mechanical parameters are obtained; determining supporting parameters of the pre-stressed anchor rod; according to the corresponding relation between the additional stress of the pre-stressed anchor rod and the mechanical parameters of the surrounding rock and the supporting parameters of the pre-stressed anchor rod, second mechanical parameters of the surrounding rock within the compression range during the supporting action of the pre-stressed anchor rod are determined; determining a surrounding rock deformation value according to the first surrounding rock mechanical parameter and the second surrounding rock mechanical parameter; comparing the surrounding rock deformation value with a preset surrounding rock deformation control
