摘　　要：分析了探地雷达高频电磁波在地下有耗介质传播过程中的衰减特性,将其应用于采矿损害治理及岩石地基工程勘察。实践表明,利用探地雷达高频脉冲电磁波的衰减特性研究地基稳定性,方法可行,取得了良好的效果,并具有很好的推广应用价值。The attenuation behaviors and mechanism of high frequency impulse electromagnatic wave during its propagation in heterogeneous subground medium are analyzed. The analysis results are applied to the engineering prospecting of infirm ground and damages caused by mining. The application results indicate that the method for studying the stability of the ground by means of attenuation hehaviors of high frequency impulse electromagnetic wave of GPR is feasible,and has good application foreground in future.
