| Abstract: | The replacement and re-erection technique of high pier and large span bridges is a hard nut to crack in the girder replacement construction.This article,through the comparative selection and implementation of the lifting scheme for the 1-40m steel composite girders of Bridge No.8 of the Yongding River on Feng-Sha-Da line,makes an introduction to the technical key and implementation process of the girder replacement and re-erection construction by the large tonnage crawler crane,which is of reference to works of similar nature. |
