波形钢腹板组合箱梁与桥梁常规结构的造价比较

Cost Comparison between Composite Box-Girder with Corrugated Steel Webs and General Structure of Bridges

在目前城市高架桥梁的设计中,预应力连续箱梁是运用最广泛的,波形钢腹板组合箱梁是一种新型桥梁结构体系。以郑州南三环东延工程为例,对波形钢腹板组合箱梁和预应力连续箱梁的造价进行对比分析,从中了解波形钢腹板组合箱梁的大致经济指标及变化规律,为以后类似工程的估算提供参考。

The prestressed continuous box girder is widely used in design of urban viaduct,but the composite box-girder with corrugated steel webs is a new type of bridge structure system.In this paper,the Zhengzhou Nansanhuan East Extension Project was studied as an example to understand the general cost index and the change law of this new structure system for reference in the future.
