地面坍塌隐患检测中三维地质雷达数据处理及隐患识别研究

Research on the data processing and risk identification of three dimensional geological radar in ground collapse risk detection

三维地质雷达作为一种高效、无损的检测技术,已广泛应用于城市道路地下病害或坍塌隐患检测中。与传统的二维地质雷达相比,三维地质雷达在隐患识别、数据融合、工作效率等方面具有突出优势,逐渐成为城市道路地面坍塌隐患检测的主要方法。笔者总结了三维地质雷达的技术优势,通过对三维地质雷达数据处理的总结研究,提炼出了一套系统的数据处理流程,通过对不同隐患的三维地质雷达图谱特征进行分析研究,总结出了不同类型隐患的识别特征及判定依据,为城市道路地面坍塌隐患三维地质雷达检测数据的处理及隐患的识别提供参考。

As an efficient,nondestructive detection technology,three-dimensional geological radars has been widely used to detect underground disasters or collapse risks of urban roads.Compared with the traditional two-dimensional geological radar,three-dimensional geological radars has outstanding advantages in risk identification,data fusion,work efficiency,and other aspects and have gradually become the primary method of urban roads ground collapse risk detection.This article summarizes the advantages of three-dimensional geological radar technology through the summary of three-dimensional geological radar data processing,extracts a system of data processing process,through the analysis of different three-dimensional geological radar profile,summarizes the different types of risk identification characteristics and determination basis,for urban road ground collapse risk three-dimensional geological radar detection data processing and risk identification provide reference basis.
