由于瞬变电磁法对未知地层中的水尤其敏感,隧道超前地质预报已引入瞬变电磁技术,论文着眼于ANSYS软件模拟瞬变电磁应用超前地质预报的可行性,建立地表半空间瞬变电磁数值计算模型模拟二维平面烟圈的扩散效应,并将数值模拟结果与理论计算结果进行分析,结论表明利用ANSYS软件来模拟瞬变电磁是可行的。

Because of the transient electromagnetic method is especially sensitive to water in unknown layer, geological predication of tunnel has introduced transient electromagnetic method. This paper focuses on the feasibility of using ANSYS software to simulate the geological predication of transient electromagnetic applications, establishes a numerical model of transient electromagnetic field in surface half space to simulate the diffusion effect of two-dimensional plane smoke ring, and the results of numerical simulation and theoretical calculation are analyzed. The conclusion shows that it is feasible to simulate transient electromagnetic field by using ANSYS software.
