Abstract

The construction process of underground engineering like tunneling would face with the risks of complex geological disasters such as water inrush and mud outburst constantly，and transient electromagnetic method which is based on the difference of resistivity between surrounding rocks and water-bearing bodies could detect and position the water-bearing structure ahead of tunnel face. However，the data quality at middle-later period is relatively poor during the practical detection process. In this paper，the uniform half-space model and the three-layer classical model are studied to investigate the applicability of transient electromagnetism to detect apparent resistivity. The results show that the late-stage data conversion is good without interference and the late-stage data conversion is worse under strong interference difference. Compared with 3 filtering de-noising algorithms aiming to optimize the data quality at middle-later period，we are certain that they can improve the signal-to-noise ratio and apparent resistivity imaging of TEM induced electromotive force under strong interference circumstances. Using the filtering algorithm compared with the traditional direct truncation method after field testing，it is found the amendments to the unstable data which occurred in the late response period partial time-channels can improve the overall apparent resistivity imaging and the resolution of the detection results by the truncation method and filtering algorithms.
