摘　　要：基于热传导理论,运用有限元方法进行了二维温度场模拟,论证了该方法的可行性,与实验结果做了对比,分析了偏差的存在原因,并进一步研究了该方法的路面检测最大厚度,对红外成像技术应用于道路检测的实施具有重要的参考意义。A new testing method infrared thermography test for concrete cavity beneath slab was developed. This method was studied through the experimental. Two-dimensional temperature field was simulated with the finite element method base on theory of heat exchange. The feasibility of this method was demonstrated. This paper compared the results of numerical simula tion with the result of test, and analyzed the reasons of windage. Then, an in-depth study was researched in the range of test. It had important reference significance to apply the infrared thermography test in the road examination.
