摘要
本文对EH4的原理、特点、注意事项及数据处理过程进行了分析说明,通过在深埋滑坡变形体探测中成功地探测出该不良地质体的走向及发育规模等空间赋存状态的实例应用,说明了该方法能够有效地探测深度1000m范围内的地质情况,测试频率为10Hz^100k Hz。并应用Voxler三维成图软件对资料进行了空间三维延拓,使探测成果以三维可视化方式直观地显示出来。
The EH4 can be effectively used to detect the geological conditions within the range of 1000 m.A successful case with this method to explore a large-scale landslide deformation body is presented. The EH4 with frequency range from 10 Hz to 100 k Hz is used for the orthogonal components of the electromagnetic field data acquisition. The relevant electrical properties of the earth are extracted from the electromagnetic profiles. The Voxler mapping software is applied for EH4 data processing,and the exploration results is intuitively displayed with the three-dimensional( 3D) visualization.
