Numerical Simulation Study on Detecting the Strike Slip Fault with the Cross Section of Electrical Resistivity

摘要:

本文从走滑断层难以探测的实际出发,讨论了其物性特征.通过对实际模型的数值模拟,讨论了纵、横向剖面电阻率的变化特征.数值模拟结果证明横向剖面和纵向剖面相比在断层探测中有明显的优越性,为走滑断层探测提出了新的思路.

Abstract:

Facing the fact that strike slip fault is hard to detect, in the paper the physical characteristics of the fault are discussed, through the numerical simulation of actual model, the different variation characteristics of electrical resistivity for vertical and cross sections are discussed also. The result of numerical simulation demonstrats that the cross sections have more marked precedence compared with the vertical section, therefore, this method puts forward a new idea to detect the slip fault.
