Abstract: Taking Beipanjiang Bridge in Guizhou Province as an example, the catenary element calculation method is adopted to calculate the erecting parameters of catwalk construction, with the consideration of unbalanced horizontal force produced by the catwalk side mid-span separation and the influences the catwalk load has on the parameters of construction control of suspension bridge. The engineering practice indicates that this method is accurate and can provide the references for the calculation of catwalk construction and the construction control of suspension bridge.

Key words: suspension bridge , catwalk , construction control , catenary ;
