市政道路路基常见隐患地质雷达图像特征分析

Image Characteristic Analysis of Geological Radar for Common Hidden Dangers of Municipal Road Subgrade

道路路基隐患对道路性能和行车安全影响重大,对于道路隐患的检测和预警至关重要。三维地质雷达因其无损、高效的优点而受到广泛应用。但现行规范中关于三维地质雷达图像特点的描述存在空白,导致图像判断准确率、隐患验证时间增加。本研究结合项目实例,对路基的疏松体和脱空的图像进行分析比对、误差分析,明确了其图像特征,从而提高图像判别的准确率,对规范中的隐患图像特征描述具有指导和借鉴意义。

The hidden danger of the road subgrade has a great impact on road performance and driving safety, and it is very important for the detection and early warning of the road hidden danger. 3D geological radar is widely used because of its non-destructive and high efficiency. However, there is a gap in the description of the characteristics of 3D geological radar images in the current specification, which leads to an increase in the accuracy of image judgment and the hidden danger verification time. Combined with the project examples, we analyzed the comparison and error analysis of subgarde loose body and cavity, and clarified the image characteristics, so as to improve the accuracy of image discrimination, which has guidance and reference significance for the hidden danger image feature description in the specification.
