Self-anchoring type mounting method of suspension bridge
The invention provides a self-anchoring type mounting method of a suspension bridge. The method comprises the steps of constructing a main pier and a side pier; erecting beams and splicing through a crane; mounting a medium supporting pier of a side span steel box beam; mounting the side span steel box beam; mounting a temporary steel tower; mounting a main span steel box beam and a temporary cable; mounting a main cable and a lifting cable; converting the systems. The method is free of the limitation of navigation of a waterway; an ultrahigh bracket cannot be constructed in the river at a gorge region with steep bank slopes, so that the input is reduced; the longitudinal moving load can be decreased, and the longitudinal moving range, so that the long-distance and large-tonnage propping and pushing can be avoided, and as a result, the risk of construction safety in longitudinal moving can be reduced; a propping pushing bracket can be avoided being scoured by flood and floating articles, so that the safety risk of construction is reduced, and the construction is sped up.
