The invention discloses a self-anchorage cable bent tower driving cross brace arranging method. The method comprises the following steps of 1 machining a cross brace body, 2 machining a steel casing pipe, 3 lifting a cross brace body and the steel casing pipe, 4 installing a jack and 5 performing welding and fixing. The overall anti-bending capacity of the cable bent tower can be improved, a transverse brace steel tube bearing beam and a steel casing pipe bearing beam are arranged inside the cross brace steel pipe and the steel casing pipe in advance respectively, then, in the installing process, the jack can synchronously act on the cross brace steel pipe and the steel casing pipe according to the designed jacking force, and then the movable connection portion of the cross brace steel pipe and the steel casing pipe is welded and fixed after the cross brace steel pipe and the steel casing pipe are in place; according to the method, under the concrete dead-weight construction load and wind load effect, the pylon root pulling stress can be greatly lowered, and therefore the pylon generate no crack; it is ensured that construction is performed in order while the construction quality is ensured; meanwhile, construction of the cross brace is convenient, and the construction safety and stability can be improved.
