摘要
为推广预应力混凝土箱梁结构在桥梁方面的应用研究,结合英屿沟Ⅱ号天桥实例,介绍了该组合结构在桥梁方面具体应用的设计思路,介绍了英屿沟Ⅱ号天桥波形钢腹板PC组合箱梁桥主梁结构、预应力体系、波形钢腹板、连接件、防腐、施工流程等的设计,为波形钢腹板PC组合箱梁结构应用于桥梁工程提供了设计经验.
In order to popularize and apply prestressed concrete box girder in bridges,combining with No.2 platform bridge in Yingyugou,the design approach of this composite structures in bridges was introduced,including such structure as main beams,arrangement of prestressed system,corrugated steel webs,connectors,anticorrosion,construction processes,etc,which provides the design experience for prestressed composite box girder structures with corrugated steel webs used in domestic bridge project in the future.
