| Abstract: | The main span of the 2nd Luzhou Yangtze River Bridge is a girder structure of a nonsymmetrical continuous prestressed concrete rigid frame.The cantilever construction method is used for its building.On account of its complicatedness,the structure systems and forces are varied during the construction procedures.Therefore,it is necessary to control the construction procedure.This paper introduces the main method and the theory of construction control.With an effective control,the results of alignment and stress of the bridge are presented,which scientifically ensure the quality and safety of the whole construction. |
