The invention discloses a landscape suspension bridge and an anchoring method for a decorative cable thereof. A main cable is arranged on a bridge tower through a cable saddle frame, the tail end of the main cable is anchored on an anchorage structure at a bridge abutment, the anchorage structure includes a bridge abutment cushion cap, an anchorage on the outer side above the cushion cap and a side wall on the inner side above the cushion cap, and the cushion cap, the anchorage and the side wall completed by integrally pouring; the upper end of the suspender is fixed to the main cable on a design position by a cable clamp, and the lower end of the suspender is anchored to a beam through a longitudinal beam; the beam is an I beam, one end of the beam is pre-buried in a pier bent cap, and the other end of the beam is welded to a steel plate and is connected with a longitudinal beam body through bolts; the longitudinal beam is composed of two pieces of box iron, and the suspender is located between the two box iron and fixed by an upper pad, a lower pad and bolts; and the longitudinal beam is poured together with the suspender in concrete at the bridge abutment and the bridge tower. The landscape suspension bridge and the anchoring method avoid fixing the suspender to a side beam flange plate, reduce the adverse effect on the structure and have certain landscape and economic advantages; and the operation and maintenance is simple, and people can use conveniently.
