摘要
从地质雷达原理出发,分析地下病害体的地球物理特征及其反映在地质雷达信号中的波组特征,同时总结城市道路常见电磁干扰物及其在地质雷达信号中的特征.结果显示:地质雷达解译中,正确识别有用信号、排除干扰信号,对提高地质雷达解译的准确性至关重要;结合工程实践,地质雷达法可在城市道路塌陷病害探测中取得较好效果.
Abstract
Based on the principle of ground penetrating radar,the geophysical characteristics of underground disease bodies and their wave group characteristics reflected in ground penetrating radar signals are analyzed.At the same time,the common electromagnetic interferences on urban roads and their characteristics in ground penetrating radar signals are summarized.The results show that correctly identifying useful signals and eliminating interference signals is crucial for improving the accuracy of geological radar interpretation.Combined with engineering practice,the geological radar method can achieve good results in detecting urban road collapse diseases.
