description The invention relates to an unbonded prestressed steel pipe confined concrete prefabricated assembled pier structure and a construction method thereof. The structure comprises a cover beam (2), a stand column (3) and a bearing platform (6) which are sequentially connected through prestressed tendons (1) in a penetrating mode. A bent cap pre-embedded energy-consuming steel bar (42) is arranged between the bent cap (2) and the stand column (3) in a penetrating mode, and a stand column pre-embedded energy-consuming steel bar (44) is arranged between the stand column (3) and the bearing platform (6) in a penetrating mode. Anchor bearing plates (13) which abut against the cover beam (2) and the bearing platform (6) respectively are arranged on the outer side of the cover beam (2) and the outer side of the bearing platform (6), anchor bolts (12) used for fastening are arranged on the outer sides of the anchor bearing plates (13), and the anchor bearing plates (13) and the anchor bolts (12) are arranged at the ends
