Self-resetting bridge pier

The invention relates to the technical field of bridge engineering, in particular to a self-resetting pier which comprises a pile foundation, a pier column, a cover beam and a pier column prestress steel strand which are sequentially arranged from top to bottom, the pier column prestress steel strand sequentially penetrates through the cover beam, the pier column and part of the pile foundation, and the top end of the pier column prestress steel strand is anchored to the top of the cover beam. The bottom end of the pier column prestress steel strand is anchored on the side face of the pile foundation, the bottom end of the pier column prestress steel strand is located on the ground, and after a strong earthquake occurs, the bottom end of the pier column prestress steel strand is anchored on the side face of the pile foundation and located on the ground. Therefore, the pier column prestress steel strand can be conveniently checked through the bottom end anchoring point, exposed out of the ground, of the pier c
