摘要 在铁路工程建设中,桥梁工程采用预应力钢筋混凝土简支T梁,具有结构简单和架设方便等优点。但是,是在施工现场修建制存梁场供梁,还是采购供梁,哪种供梁方案更为经济,此文以某铁路综合货场桥梁建设为例,对2种供梁方案所需费用,根据概算编制办法和相关标准进行计算、分析与比较。结果表明,在现场修建制存梁场供梁更为经济。 In railway engineering construction, the bridge project uses the prestressed reinforced concrete simply supported T beam, which has the advantages of simple structure and convenient installation. However, the economic performance of site precasting scheme and purchase scheme need to be analyzed. Taking the bridge construction in a comprehensive railway freight yard as an example, the cost of two schemes are calculated, analyzed and compared according to the budgetary estimate making method and the relevant standards. The results show that the beam supply scheme of site construction of girder fabrication andstorage yard is more economic.
