摘要
通过对某运营25年的钢结构悬索桥的外观检查、主缆线形和钢桁架变形测量及现场结构动力特性试验,从桥梁结构外观现状、主缆安全系数、钢桁架的变形和静动力特性等诸方面分析了该桥目前的实际工作状态,并做了较为全面的性能评估,可为该桥今后的运营管理及扩能改造提供参考。
According tO the inspection of the appearance of a steel truss suspension bridge served for 25 years, the dynamic test and the measurement of the truss＇s deformation and the alignment of the main cable, the actual working condition of the bridge, including the safety factor of the main cable, the deformation of the steel truss and the behavior of static and dynamic, are ananlysed. Also the overall assessment and suggestion for this bridge are presented, which also provide the references for the operation management and capacity enhancement project.
