摘要
为了有效地识别出梁体损伤裂缝所在的位置,尤其是对于不易被察觉的损伤,利用小波分析所具有的识别突变信号的特点,研究了小波技术应用于桥梁结构损伤检测,分析了实测结果,表明小波变换在桥梁结构裂缝检测中切实有效。
To identify the position of the unnoticeable beam crack correctly, this paper discussed the, result of wavelet analysis in identification of bridge structural damage ,according to the feature of testing abrupt signals with wavelet transformation. The analysis indicated that wavelet analysis is a powerful tool in bridge crack detection.
