钢板组合梁与普通混凝土箱梁桥对比分析

Comparative Analysis of Steel Plate Composite Beam and Ordinary Concrete Box Girder Bridge

济祁高速淮河特大桥引桥规模较大,引桥造价占到整个大桥总造价的80%以上,本文主要通过材料使用性能、综合成本(即施工进度、工序成本等综合效率成本)、结构耐久性、环境保护、桥梁景观等因素,对钢板组合梁桥和预应力混凝土小箱梁桥进行了论证和分析。

The approach bridge of Huaihe River Bridge of Jiqi Expressway is large,and the cost of approach bridges accounts for more than 80%of the total cost of the whole bridge.Based on the material use performance,comprehensive cost(ie,construction efficiency,process cost and other comprehensive efficiency costs),structural durability,environmental protection,bridge landscape and other factors this paper demonstrated and analyzed the steel plate composite girder bridges and prestressed concrete small box girder bridges.
