Chen Yunmin Wu Shiming Xia Tangdai(Department of Civil Engineering)
Based on the study of spectral analysis of surface waves method by authors in recent years, the fundamentals and the in-situ tecting teshnique of inspecting the qualification of highway structures by this method is presented. Its reliability is confirmed by aodestructive testing method. A comparison with the destructive testing method is made through applications , showing that the presented method is simple and non-destructive and can provide more parameters to evaluate the quality of structures. This paper is useful to inspecting the quality of highway structures and airport runway or large concrete components.
