蒲山特大特为大跨径桁架式钢管混凝土下承式系杆拱桥,空间结构复杂,施工难度较大,为了保证该桥施工质量和施工安全,必须对桥梁建设的整个过程进行施工监控。采用应力遥测系统对该桥进行监控,监测结果表明:拱肋主要承受压力、弯矩较小,桥梁拱肋受力均在桥梁设计规范规定范围之内。 Pusan ​​extra large is a long-span truss type CFST under-span tied arch bridge with complex space structure and difficult construction. In order to ensure the construction quality and construction safety of the bridge, the whole process of bridge construction must be monitored. The bridge is monitored by stress telemetry system. The monitoring results show that the arch rib is mainly under pressure and moment, and the load of the bridge arch rib is within the scope of the bridge design code.
