The objective of this study is to research the key technology of the construction control of a steel box basket-handling arch bridge.The key technology of the new method of the once tensioning (the cable force of this segment needs to be tensed only once) is studied in this paper, A method of determining the reasonable buckling cable force and the precamber in the process of assembling the long span arch bridge is applied to solve the main problem in the construction control of the whole welding steel box basket-handling bridge. Reasonable results of buckling force and precamber are maintained...
