大型斜拉桥索塔钢锚梁-钢牛腿制造相关问题探讨

摘要:

索塔锚固结构是大型斜拉桥主要受力结构,质量要求高、制造难度大。本文针对钢锚梁-钢牛腿这种锚固结构,结合工程实例,对其结构特点及制造难点、制造过程中的注意事项、焊接变形控制措施等进行了介绍,并提出了一些设计优化建议,可供类似工程借鉴。

Abstract:

Cable tower anchor structure is the main force structure of large cable-stayed bridge, which requires high quality and is difficult to manufacture. Based on the anchoring structure of steel anchor beam and steel leg, the paper introduces its structural characteristics, manufacturing difficulties, points for attention in manufacturing process, welding deformation control measures, etc., and puts forward some suggestions for design optimization, which can be used for reference in similar projects.
