雷达法检测路面厚度的精度分析与建议

短脉冲雷达检测沥青路面厚度是一种无损、高效并且能连续检测的方法,具有广阔的应用前景和巨大的社会经济效益。由于目前雷达法检测路面厚度受到较多因素的影响,导致其检测结果存在一定的误差,通常在交工验收时以钻芯法检测结果为标准,该文通过结合实际工程的应用,深入分析雷达在检测路面厚度方面存在的影响因素,包括设备参数设置、天线频率的选择、介电常数的标定和距离标定和路面施工水平等,通过控制各因素的影响以提高检测结果的精度,并给出建议,为今后雷达检测技术的发展提供参考依据。

Short pulse radar detecting thickness of asphalt pavement is a kind of condition, efficient and continuous detection method, with a broad application prospect and huge social and economic benefits. Because the ground penetrating radar method detection of pavement thickness influenced by many factors, lead to the test result has certain error, usually by the method of core at the completion of the acceptance test results for the standard, this article through the in-depth analysis of the application of combined with the actual project of radar in the detection of pavement thickness of influencing factors, including the selection of equipment parameters, antenna frequency, dielectric constant, distance calibration, pavement construction level, etc., by controlling the influence of various factors to improve the accuracy of test results and give Suggestions for the future provided a reference for the development of radar detecting technology.
