向阳河特大连续梁桥的结构设计与研究

Structural Design and Study of a Continuous Girder Bridge

简要介绍了向阳河特大桥连续梁的主体结构设计,桥梁跨径布置为14×30 m+(48 m+80 m+48 m)+21×30 m,主桥采用变截面预应力混凝土连续箱梁,实体墩,桩基础;引桥采用装配式预应力混凝土连续箱梁,拱形墩,肋板台,桩基础。设计采用了新颖美观的拱形墩结构,采用了智能张拉和真空压浆等新技术新工艺,对同类型桥梁的设计有一定的参考价值。

This paper describes the design of the main structure of a continuous girder bridge.The span arrangement of the bridge is 14 × 30 m +(48 m+80 m+48 m) + 21 × 30 m.The main bridge is the variable cross-section prestressed concrete continuous box girder bridge with entity pier and pile foundation.The approach bridge is the prefabricated prestressed concrete continuous box girder bridge with arched pier,rib abutment and pile foundation.The fashionable and attractive arched pier structure is used in design.The new technology and new technique of intelligent tension and vacuum grouting are also used in design.The relative experience can be referred for the design of the similar bridges.
