悬索桥锚索拉杆更换设计研究

Study on Design of Anchor Cable Tie Rod Replacement of Suspension Bridge

为了提升营运桥梁安全防护能力,以跨径636 m的某单跨钢桁梁悬索桥为例,对悬索桥主缆锚固系统锚索拉杆更换进行设计研究。主要探讨悬索桥锚固系统索股连接件中拉杆更换设计时的施工及监测要求、防腐措施、材料性能要求等,对于营运桥梁的预防性养护工程和提升营运桥梁的安全防护能力具有较大的参考价值,指导借鉴作用显著。

In order to improve the safety protection capacity of operating bridges, taking a single-span steel truss suspension bridge with a span of 636 m as an example, the replacement of anchor cable tie rods of the main cable anchoring system of the suspension bridge is designed and studied. The construction and monitoring requirements, anti-corrosion measures and material performance requirements in the design of tie rod replacement in the cable strand connector of anchoring system of suspension bridge are mainly discussed, which has the great reference value for the preventive maintenance engineering of operating bridges and improving the safety protection ability of operating bridges. And the guiding reference function is obvious.
