摘要
本文针对路基结构内部经常出现的裂纹、松散、空洞、离析等缺陷,提出了一种利用瞬态表面波频谱分析法无损检测路基结构质量的基本原理和检测方法。通过现场试验结果表明:瞬态表面波频谱分析法能较好地反映路基结构内部质量的分层介质情况,且检测方法简单、可靠。它对于各类路基结构质量评定具有较高的工程实用价值。
A new nondestructive method to detect the quality of the pavement structure by using transient Rayleigh surface wave spectral analysis is proposed with respect to the defects such as crackle, loose, space, dispersed etc. , which often occur inside the pavement structure. The testing results show that the transient surface wave spectral analysis method can effectively detect the default of the layered media inside the pavement structure. Furthermore, the method is simple and reliable during detection. It shows a good practicability for the estimation of the quality of various pavement structure.
