Novel cantilever construction steel box arch bridge structure without temporary measures

The invention discloses a novel cantilever construction steel box arch bridge structure without temporary measures. The structure is formed by combining a steel box arch rib, a concrete skewback, a plurality of suspenders and a bridge deck structure. By increasing the cross section size of the arch rib and depending on self structure cantilever construction, the arch rib can bear the structure stress in a finished bridge state and can meet the stress requirements of various working conditions in the construction stage; jacking force can be applied to the two sides of the arch rib before the arch rib is closed, the stress of the arch rib and the arch support is adjusted, and the purpose of saving the construction cost is achieved; in the construction process of the arch ribs, closure and arch forming of the arch ribs can be achieved without the help of external auxiliary facilities, a large number of temporary measures needed in the previous arch bridge arch rib construction process are saved, the arch bridge
