| Abstract: | Multi-electrode Electric Method (MEM) is an effective tool in landslide survey. A suitable working scheme in-situ and the corresponding data interpretation approach are the fundamentals for obtaining believable results. Finite element 2D forward modeling was conducted on four types of standard electric models; respectively named the homogeneous soil landside, bedding landside, sliderock landside, and beveling landside; under the utilizations of four different types of electrode arrays; respectively namely the Wenner array, Schlumberger array, dipole-dipole array and pole-pole array. The capacities of different arrays and the resistivity responses of different types of sliding faces were determined based on the resultant standard electric profiles. An innovative data processing procedure called the ratio parameter method was proposed for locating sliding faces under complex geological conditions. A series of case histories for landside survey were given. |
