摘要
本文通过地下空洞探测实践,构建和分析了地下空洞的地质-地球物理模型及其土体缺陷特征,给出地下空洞的探地雷达异常波形特征及其识别方法,提出一种不同于当前通用方法的地下空洞的探地雷达图像解释技术。
According to the underground voids detection practice,the geological and geophysical model of underground voids and the characteristics of the soil mass defects is built and analyzed,the abnormal GPR waveform characteristics of underground voids and its identification methods are proposed, a new underground voids GPR image interpretation techniques that different from the currently method is put forward.
