The invention discloses an anchorage pier structure suitable for surrounding rock deformation, belonging to the field of building construction. The anchorage pier structure suitable for surrounding rock deformation comprises an anchorage pier, a steel strand and an anchorage device, wherein one end of the steel strand penetrates through a locking hole on the anchorage pier and is locked on the anchorage pier through the anchorage device; the anchorage pier structure further comprises a first anchorage plate, a second anchorage plate and an elastic part, wherein the first anchorage plate and the second anchorage plate are arranged between the anchorage pier and the anchorage device; the steel strand penetrates through the lock hole in the anchorage pier, then penetrates through the first anchorage plate and the second anchorage plate in sequence, and is finally connected to the anchorage device; the elastic part is arranged between the first anchorage plate and the second anchorage plate. The self-adaptive regulation of the anchorage pier structure during surrounding rock deformation is realized, so that enough anchorage force can be provided at an initial anchorage stage, and therefore, the surrounding rocks are prevented from being unstable; meanwhile, enough deformation can be reserved for being adaptive to the great deformation condition which possibly appears in later-stage surrounding rocks. Besides, the anchorage rope is prevented from being stretched and pulled for the second time.
