该桥为双线铁路桥，采用整体焊接节点钢行梁，它是国内首次采用的新型钢梁结构，是铁路钢桥建设的新的里程碑。其主要特点是，结构新、焊缝多、受力复杂、加之我国火车货运载重量为世界之最，对其焊接质量、焊接接头性能要求苛刻。为确保质量，课题组重视科研与生产实际结合， The bridge is a double-track railway bridge, the overall welding node steel beam, it is the first time the new steel beam structure is used, is the railway steel bridge construction a new milestone. Its main features are: new structure, many welds, complex force, combined with China’s railway freight carrying capacity of the world’s most, its welding quality, demanding performance of welded joints. To ensure quality, the research group attaches importance to the actual combination of research and production,
