Based on geological radar penetrating practice for soil and stone dam hidden dangers of reservoirs in northwestern loess areas and from the variations of the disturbance , pore ratios and water contents of the soil bodies in the percolation positions , the authors analyzed the variations of geological waveform characteristics and waveform phase axis continuation , and summed up the graph characteristics of the percolation hidden dangers in different periods
摘要通过西北黄土地区水库土石坝渗流隐患探地雷达探测实践，从渗流部位的土体扰动、空隙比、含水量的变化入手，分析探地雷达波形特征变化、波形同相轴连续性的变化，总结了渗流隐患不同时期的探地雷达图像特征。
