中小跨径桥梁常规上部结构技术经济指标分析

Analysis of Technical Economic Index of Regular Superstructure of Medium-small Span Bridges

在调查研究、计算基础上,对高速公路桥梁、城市立交—高架体系中小跨径桥梁常规上部结构的技术经济指标进行了比较,从而提出了中小跨径桥梁常规上部结构经济形式。以利于降低工程造价,提高项目收益率,推进桥梁建设项目管理、设计施工标准化。

Based on investigation and calculation, a comparison is made of the technical economic indices of medium-small span bridges with regular superstructure between bridges on the expressway and those in the urban interchange-viaduct system, with the proposed economical form of the regular superstructure, which may reduce the engineering cost, raise the benefit factor and promote project management and design standardization in bridge construction.
