| 摘 要： | 本文在基于小波包能量谱的结构损伤预警理论基础上,建立了大跨悬索桥损伤预警方法,并以润扬大桥悬索桥为例,详细研究了损伤预警指标的损伤适用性和损伤敏感性.分析结果表明,采用基于小波包能量谱的结构损伤预警指标能有效地发现大跨悬索桥桥面结构的损伤,并且不同预警指标的损伤敏感性不同.

| Abstract: | The damage alarming method for long-span suspension bridges is set up in this paper on the basis of the structural damage alarming theory based on wavelet packet energy spectrum. Through the Runyang Suspension Bridge, the damage alarming capacity and sensitivity of the damage alarming indices are discussed in detail. The analysis results reveal that reinforced beams' damages can be detected effectively by the damage alarming indices based on wavelet packet energy spectrum, and the three indices's ensitivities for damage are different. |
