摘要
本文提出了采用表面波频谱分析法检测道路结构质量的基本原理和现场测试方法,并用破损性试验的结果检验它的可靠性。工程应用表明该法具有测试简便,无破损和能提供比较全面的质量评定指标等优点。本文对高等级公路、机场跑道和大型混凝土受力构件的质量检测具有较大的实用价值。
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.
