探地雷达检测公路结构层隐含裂缝实用方法研究
|
摘要
本文在简要介绍探地雷达基本原理的基础上,详细介绍了作者最近完成的"多层均匀层状介质中的垂直裂缝对雷达波场响应的数值模拟和物理模拟实验研究"成果,通过与实际的公路工程检测结果对比,三者表现出很好的一致性.研究结果表明,采用探地雷达检测公路结构层中的隐含裂缝,理论条件是充分的,实践上是可行的,检测方法本身实用性较大,检测结果直观、可靠.
This paper discusses the detection of concealed cracks under highway surface.We described the ground penetrating radar method and the numerical and physical modeling results of the effects of vertical cracks on GPR wavefield in horizontally layered homogeneous media.Comparisons show that the modeling results are in good agreement with those from project examination.Both theoretical study and practice prove that detection of concealed cracks in highway structural layers with GPR is correct in theory and feasible in practice.
