Sensitivity of galvanic and inductive Induced Polarization methods to the Cole-Cole parameters

Эффекты Последействия В Методе Переходных Процессов: Индукцонно-Вызванная Поляризация

“…Иногда возникают затруднения, связанные с необходимостью объяснить, почему при проведении съёмок методом ВП с заземлёнными линиями наблюдаются значительные аномалии поляризуемости, а проявления ВПИ отсутствуют, или же аномалии ВП и ВПИ не коррелируют [García-Fiscal, Flores, 2018;Macnae, Hine, 2016;Seidel, Tezkan, 2017]. На наш взгляд, это объясняется тем, что физика ВПИ отличается от той, на которой основан метод ВП.…”

Estimation of frequency domain soil parameters of horizontally multilayered earth by using Cole–Cole model based on the parallel genetic algorithm

“…It has been confirmed that Cole–Cole model can describe the frequency dependence of soil parameters observed from field data [1–4]. A numerical simulation experiment was implemented to study the potential and limitations of estimating Cole–Cole model parameters by using transient EM methods [16].…”

“…Soil conductivity and permittivity can be expressed by soil complex conductivity. It has been verified that Cole–Cole model can describe soil complex resistivity or complex conductivity observed from field data [1–4].…”

“…Paper [1–3, 16] studied the inversion of Cole–Cole model parameters of homogeneous ground. Paper [4, 17] developed inversion algorithms with considering two‐layer model. However, as mentioned above, two‐layer model may not be accurate enough.…”

“…There are two kinds of implementation plans in the optimisation of Cole–Cole model parameters. One is estimating the DC soil parameters and Cole–Cole model parameters simultaneously, such as paper [4]. The other one is obtaining DC soil parameters and Cole–Cole model parameters by two steps [17].…”
