The utility model discloses a novel combined anti-sliding pile structure which comprises a reinforced concrete anti-sliding single pile, a steel pipe diagonal brace and a basement, wherein concrete is poured into the steel pipe diagonal brace, of which one end is fixedly connected with the anti-sliding single pile, and the other end is inserted in the basement. The portion of the steel pipe diagonal brace inserted in the basement is an anchoring section. The pile structure solves the problems that the anchor cable of a conventional anti-sliding pile is relax in stress, the conventional anti-sliding pile is narrow in application scope and is easy to rust; displacement deformation on the top of the pile is great and difficult to control, soil tends to slide out; and actual anti-sliding effect and retaining ability are poor. The novel combined anti-sliding pile structure effectively controls the displacement deformation on the top of the pile, and is wide in application scope, reasonable in integral bearing capability and excellent in anti-sliding and retaining performance.
