摘要
以某大跨度连续箱梁桥为背景,对不中断交通条件下关键截面动挠度进行跟踪监测。通过小波分析等数据处理手段获得了大桥动挠度幅值变化、概率密度分布等统计特征参数,应用多种动挠度测试手段验证了测试结果的可靠性。监测成果为今后桥梁技术状况长期健康监测提供了比较基准,对同类桥梁受力状态评价和维护策略的制定具有重要参考价值。
With a large span continuous beam bridge as the research background, the dynamic deflection of critical cross section under the condition of uninterrupted traffic is monitored. The dynamic deflection amplitude, the probability density distribution and other Statistical parameters are obtained by using wavelet analysis and other data processing means, and the reliability of the test results was verified by comparative test. The monitoring results provide a foundation for future long-term health monitoring, it is of great reference value for mechanics evaluation and maintenance strategies.
