W-shaped pier

The invention discloses a W-shaped pier. The W-shaped pier comprises an upper pier body, a lower pier body and a bent cap; the upper pier body is W-shaped; the top of the upper pier body is connectedwith the bent cap; the bottom of the upper pier body is connected with the lower pier body; the lower pier body is a double-column pier. According to the W-shaped pier, the upper pier body on the upper portion of the W-shaped pier is W-shaped and can better adapt to arrangement of the support of a wide-body beam bridge; cantilever arms are short, so that stress is reasonable, and therefore, the defects of a traditional Y-shaped single-column pier in the wide-body beam bridge are effectively overcome, and construction is convenient; the upper pier body has a cavity, so that materials are saved;meanwhile, the lower pier body of the lower portion of the W-shaped pier is a double-column pier, and compared with a three-column pier or large-size pier body design adopted by a traditional wide-body beam bridge, such a str
