近十几年来,悬索桥钢箱梁的耐久性问题非常突出,世界各国桥梁工程师都面临着如何正确的设计与制造钢箱梁这一大课题。主要对悬索桥钢箱加劲梁设计与制造技术进行了分析研究,尤其是对钢箱梁面板单元设计与制作、面板单元厚度选择、横隔板单元设计制作、U肋嵌补段处理等方面进行了较深入的探讨,并提出了相关应用建议,为避免今后新建桥梁发生疲劳裂纹,确保桥梁寿命有着借鉴意义。
In recent ten years, the durability of suspension bridge steel box girder is very outstanding. Bridge engineers all over the world are faced with the big issue of how to design and manufacture steel box girder correctly. The design and manufacture technology of steel box stiffening girder of suspension bridge are mainly analyzed, especially for the design and fabrication of steel box girder panel unit, the thickness selection of panel unit, the design of diaphragm unit, More in-depth discussion, and put forward the relevant application recommendations, in order to avoid fatigue cracks in new bridges in the future to ensure the life of the bridge has reference.
