| Abstract: | Huangshagang bridge which uses( 60 + 100 + 60) m prestressed concrete continuous beam is a double-track bridge on Lianyungang-Yancheng railway,and its main piers are in round shape for flood discharge. In view of the characteristics of short cantilevered cap and thin-octagonal bearing platform,the structures are calculated respectively with bracket and combines strut-tie theory. The structural types and design fundamentals of the substructure of this bridge are illustrated and the construction of the foundation is introduced briefly. |
