摘要
受公铁合建主桥通航净空以及纵坡小、梁高的影响,导致引桥桥长、桥墩高度高,桥梁工程规模大。结合一般区段桥梁、过江通道北引桥、跨宁启铁路和通扬运河特大桥等重要节点设计方案,对桥型方案进行了研究。优选了经济、合理的上下部构造型式和跨度,保证工程质量,最大程度地降低工程造价。
The approach bridge is long and its piers are very high because of the influences by the data of longitudinal gradient,depth of beam and the navigational clearance of the highway and railway bridge’s main parts. This paper studied main bridge joints design scheme for general section bridge,north approach bridge of river-crossing pathway,acrossing Nanjing-Qidong Railway and Tongyang Canal Bridge. This study tried to find an efficient and reasonable plan of substructure type and span for ensuring the engineering quality and reducing the project cost.
