Abstract

Focus on error control during fabricating and suspended splicing of box girders with segmentation method. After the analysis of the error reasons, and the combination with practical engineering—Sutong B2, it discussed control method, computing method and sensitive analysis method of linear control of prefabricated pre-stressed continuous beam bridge assembly with short line method.

Keywords
