Study on High Density Electrical Response Characteristics and Application of Buried Faults
[Purposes]In order to explore the detection effect of different devices of high-density electri-cal method on faults with different dip angles,the detection effect of high-density electrical method Wenner alpha,Wenner beta,Wenner gamma and dipole device on faults with different dip angles was studied.[Methods]Different dip fault models are established by parameter design,and the results are ob-tained by forward calculation.Then,the least square method was used to invert the forward modeling re-sults of fault models with different dip angles.[Findings]Compared with the results,it was found that the optimal recognition device of high-density electrical method for detecting fault dip Angle was Wenner alpha,and the matching degree between the recognition results and the set values was up to 96.1%.[Conclusions]The fault is embedded in the test site and the Wenner alpha device is used to de-tect it.The results verify that the high density electrical Wenner alpha device has the best fault response effect and can effectively determine the fault occurrence information.The measured results are basically consistent with the numerical simulation results.
