摘要
采用新一代三维地质雷达Raptor45 联合二维地质雷达,在湖南长沙某道路开展了地下灾害快速探测研究,快速有效分辨出地下管线、人工构造物等地下结构物和地下疏松体、脱空、空洞等城市道路地下灾害.研究结果为新一代三维地质雷达进一步应用于道路塌陷、地下空洞、地面疏松等地下灾害探测提供了示范案例.
Abstract
Using the new-generation 3-D ground penetrating radar,Raptor45,in conjunction with 2-D geological radar,a rapid underground disaster detection study was conducted on a road in Changsha,Hunan Province.This study effectively identified underground structures such as pipelines and artificial structures,as well as subsurface anomalies like loose bodies,evacuations,and cavities associated with urban road disasters.The results serves as a demonstration case for the further application of new-generation 3D geological radar in the detection on underground disasters such as road collapses,subsurface cavities and ground loosening.
