The invention discloses a few-circulation sling graded tension construction method of a concrete self-anchored suspension bridge. Sling tension adopts few-circulation graded tension control; grading refers to that each sling is tensioned in three stages; sling force of an ideal sling is P, and then the tension is conducted in three stages, namely 2/4P, 3/4P and P; and few-circulation refers to that the 74 slings of the whole bridge are tensioned in three batches totally; a sling tension facility and a main sling saddle pushing facility are required to be designed and constructed before tension construction; the sling tension facility comprises tension arm braces, tension jacks, tension nuts, and tension extension bars; and a counterforce rack is the key device in the main sling saddle pushing construction. With the adoption of the few-circulation sling graded tension construction method of the concrete self-anchored suspension bridge, the time of sling tension is reduced to 3; the construction method has the advantages that (1) the times of the repeated sling tension and cable saddle pushing are reduced; (2) a construction safety risk is reduced; (3) a construction period is shortened; (4) the occupation of project department personnel and machine resources is reduced; and (5) the construction cost is lowered.
