K.柯金()等人曾研究过断距为无限大的断层的正演问题,不过,一般断层的断距总是有限的,因此本文要讨论的是有限断距垂直断层的大地电流法正演问题,所运用的解法仍旧是位论上常用的保角变换法。垂直断层的大地电流场正演问题设高电阻岩层的电阻为无穷大,其上复盖层是均匀的,电阻率为ρ,断层的错动角为90°.如图1那样选直角坐标系.设z平面上的复位函数为w(z)=φ+iψ,ζ平面上的复位函数为w[F(ζ)]=φ+iψ=w(ζ),z=F(ζ)是保角变换函数,在ζ平面上的大地电流场电场强度复向量
K. Kejin et al. Have studied forward modeling of faults with infinitely long fault intervals. However, the general faults have only a finite number of faults. Therefore, this article discusses the earth fault current method Forward problem, the use of the solution is still used in the theory of conformal transformation. The vertical fault of the earth current field forward problem set high resistance rock resistance is infinite, the cover is uniform, the resistivity ρ, the fault angle of the fault is 90 °, as shown in Figure 1, select the rectangular coordinate system. Let the reset function on the z plane be w (z) = φ + iψ and the reset function on the ζ plane be w [F (ζ)] = φ + iψ = w Transformation Function, Complex Vector of Field Electric Field Intensity in ζ Plane
