| Abstract: | With the increase of overpass bridge project, the analysis on spatial structure in prestressed concrete continuous box girder has very practical significance. Based on the structure and stress characteristics of prestressed concrete continuous box girder, this paper summarizes the analysis method of concrete continuous box beam structure mechanics. The application of beam grillage theory, the stress of concrete continuous box girder structure is discussed, and the effect of prestressed structure is emphasized. |
