直流供电时各向异性地壳的电场分布

Electric-Field Distribution in Anisotropic Earth Crust during Supply of Direct Current

以垂直于介质主轴方向的平面作为两种介质的分界面研究,对埋在较浅地表中的直流电极,以及其向大地供电而引起的各向异性地壳中的电场分布.应用电磁学中的镜像法和静电比拟方法,计算其电位、场强的表达式.所得出的结果,可运用于地质探勘、河堤隐患探测和分析地质状况.

During the electrodes buryied beneath the shallow earth surface were supplied with direct current, the electric-field distribution in anisotropic earth crust could be calculated by applying image method and electrostatic analogue method in electromagnetics. Thus the expressions of electric potential and electric-field intensity were obtained.The results could be applied to geologic exploration and detection of riverbank hidden trouble and thus could be served as an effective basis for analysing geologic condition.
