The utility model relates to a partially cable-stayed bridge separating pipe cable saddle allowing a single steel strand to be replaced, and belongs to the technical field of bridge structural parts. The cable saddle comprises an anchor bearing plate (1), reinforcing ribs (2), a steel pipe bundle (3) and a steel hoop (4), wherein the steel pipe bundle (3) is composed of N polygonal steel pipes (5) and M gap filling steel rods (6), the shape of a cross section inner cavity of each polygonal steel pipe (5) is an equilateral or inequilateral polygon, the included angle between the two lower adjacent sides of the polygon of the cross section inner cavity of each polygonal steel pipe (5) is an acute angle, all the polygonal steel pipes in the outermost layer of the steel pipe bundle (3) are fixed in a spot welding mode, the interior of the gap between every two adjacent polygonal steel pipes on the outermost layer of the steel pipe bundle and the interiors of the gaps between the polygonal steel pipes on the outermost layer and the gap filling steel rods are protected through gas to be welded into a whole, and the assembled and welded steel pipe bundle (3) is tightly wrapped by the steel loop (4). According to the cable saddle, not only can the unbalance force be resisted in the constructing and operating stage of an inclined cable, but also the single steel strand in the inclined cable can be replaced, and manufacturing cost is low.
