摘　　要：地铁隧道空洞是交通运行及周边环境的重大隐患,对地下空洞的探测方法及应用研究具有重要意义。通过工程实例探讨GER-10地质雷达对地下空洞探测的方法以及应用效果。为调查道路空洞探测的分布特征,在研究区域布设了10条测线,探测测线长度共5 150 m,探测范围宽度约为40 m进行数据采集;通过对雷达数据的处理和解译,获得清晰的图像特征,得出结论:基层轻微不严实1处,基层含水率达4处,其余几处结合道路实际情况综合分析,道路探测无空洞现象。经过开挖验证得到GER-10地质雷达能够准确地查明塌陷空洞的位置和发育程度等情况,解译处理结果明显可靠。实践表明GER-10地质雷达为空洞探测提供了安全、快速和准确的方法,可为地铁隧道施工及防治提供数据支持和参考。Subway tunnel cavity is a major hidden danger to traffic operation and surrounding environment, which is of great significance to the detection method and application research of underground cavity. The method and application effect of GER-10 geological radar for underground cavity detection are discussed through engineering examples. In order to investigate the distribution characteristics of road cavity detection, 10 survey lines were set up in the study area, with a total length of 5,150m and a detection range of about 40m for data collection. Through the processing and interpretation of radar data, clear image features are obtained. It is concluded that the base layer is slightly loose in 1 place, the moisture content of the base layer is large in 4 places, and there is no cavity phenomenon in the road detection according to the actual situation of the road by comprehensively analyzing other places.. It is verified by excavation that the GER-10 geological radar can accurately identify the location and development degree of the collapsed cavity, and the interpretation and processing results are obviously reliable. The practice shows that GER-10 geological radar provides a safe, fast and accurate method for cavity detection, and can provide data support and reference for subway tunnel construction and prevention.
