| 摘 要： | 针对常规直流电测深的应用情况,改革布极方式,研究提出梯度测深剖面法。该法能简化布极工序,可用多台接收机或多通道电测仪在多个电测深点上同时(连续)观测,大大提高工作效率。其装置有三极测深、四极测深和中梯测深等,其观测剖面上由于采用供电极稀设方式,能很好地适应二维正反演计算网格,宜于获得带地形的电阻率、极化率断面,实现电测深数据的层折成像。目前,该梯度测深方法已应用于金属矿勘查和工程勘察之中,取得成效。 |

| Abstract: | According to the practical application of DC sounding, this paper puts forward a new gradient sounding profiles method. The surveying system can simplify the working procedure through using more than one receiver or multi-channel electrical measuring instrument in a number of electrical sounding points at the same time. Moreover, the gradient sounding system includes tri-electrode gradient arrangement, dipole-dipole gradient array and central gradient array, which is suitable to 2-D inverse interpretation. The system has been applied to metallic ore exploration and engineering investigation successfully. |
| Keywords: | gradient electrical sounding profiles DC sounding current distance three-pole sounding central gradient sounding |
