Study on Key Design Technology of Irregular Widened Precast Segmental Box Girder for Urban Interchange
Combined with the common widening form of urban interchange,the design conception of the irregular widened precast box girder is carried out,and a reasonable widening scheme is proposed.The mechanical performance of widened precast segmental box girders is analyzed,and its key structures are optimized to improve the standardization and assembly efficiency of the widened precast segmental box gird-er,and to expand the application range of precast segmental box girder in the urban interchanges,which has certain reference value for the design of similar bridges.
