【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。更多还原

【Abstract】 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.更多还原
