简支T梁制架与购架方案的技术经济比选

Technological and economic comparison of simply supported T-beam support and purchasing support scheme

详细讨论了应用于铁路简支T梁桥的预应力钢筋混凝土T梁的预制架设与购买架设两种施工方案,并以某铁路项目为例,探讨了在该项目中如何对两种施工方案进行比选,最终确定出技术经济合理的施工方案。

This article specifically introduces prefabricated support and purchasing support construction schemes of prestressed steel reinforced concrete T-beam applied in railway simply supported T-beam bridge. Taking the railway project as an example, it compares the two construction schemes in light of the Droiect, and finally determines economical and technological construction scheme.
