| 摘 要： | 基于钢筋混凝土梁信号采集试验，选用恰当的小波基函数，利用小波分析技术在信号处理和数据分析领域的优势，通过小渡分析对信号进行分解和重构，分析桥梁结构在振动时振动信号的奇异性，最终可实现桥梁健康监测中的损伤预警和对结构工程损伤的早期诊断，从而为结构的维修加固提供可靠的依据。

| Abstract: | Based on signal collection test of steel-reinforced concrete beams, the right wavelet function is chose and the advantage of wavelet analysis technology in signal processing and data analysis field the vibration damage can is taken to decompose and reconstruct the signal through wavelet analysis. What＇s more, signals are analyzed be realized, thus it The early warning towards damage and confirmation of structural provides a reliable basis for the maintenance and reinforcement of structure. |
