引言电阻率法野外测定结果可用视电阻率空间表示,即用视电阻率等值线断面图表示.工作时,在地面的一条测线上布置一系列测深点.测深点在线上的水平位置由x座标确定.将每个测深点测得不同极距(a)的观测值ρ(x,a)分别标在相应测深点下方“深度”为a处的点上.勾绘等值线即构制成所观测的视电阻率空间断面图,图中等值线的形态能反映实际空间的真电阻率分布情况,甚至可用来进行定量解释.本文只讨论二度体问题.
Introduction The field resistivity method can be expressed in apparent resistivity space, that is, the apparent resistivity isosurface cross-sectional view. When working, a series of sounding points are arranged on a survey line on the ground. The position is determined by the x-coordinate, and the observed values ρ (x, a) of different polar distances (a) measured at each sounding point are respectively marked at the points below the corresponding sounding point “depth ” at a. The contours of contour lines are constructed into observed spatial sections of apparent resistivity, the contours of contour lines can reflect the distribution of true resistivity in real space, and can even be used for quantitative interpretation. .
