摘要
为明确雷达检测二维剖面图中道路深层病害类型与影响范围,通过雷达检测设备与pavecheck软件提取道路每个区域的相对介电常数数值,基于复合材料介电模型计算道路病害区域的介电常数波动范围,提出一种针对道路沉陷、松散类病害区域的图像模拟方法,可用于分析道路病害区域介电特性的波动规律.研究表明:通过该种解译方式得到的模拟图像可以明确区分道路深层结构病害类型;该种解译方式可以准确计算病害区域的影响范围.
In order to clarify the types and influence ranges of deep road diseases in the 2D profile detected by radar,the relative dielectric constant of each area of the road was extracted by radar detection equipment and pavecheck software.Based on the composite dielectric model,the fluctuation range of dielectric constant in road disease areas was calculated,and an image simulation method for road subsidence and loose disease areas was proposed,which can be used to analyze the fluctuation law of dielectric characteristics in road disease areas.The research shows that the simulated images obtained by this interpretation method can clearly distinguish the types of deep structural diseases of roads.This interpretation method can accurately calculate the influence range of the disease area.
