应用大地电磁测深法二维正演程序,对不同情况下存在横向电性分界面的模型进行了正演模拟计算,得到了磁场的垂直分量,并计算了倾子的实部、虚部、振幅和相位资料,然后分别对不同情况下理论模型所形成的异常特征和其规律进行了分析研究.研究表明,倾子资料对地下介质中存在的横向电性分界面反映明显,但其不同分量对横向电性分界面的反映特征和反映能力各不相同.通过对理论模型中倾子资料特征规律的分析和总结,为大地电磁法中实测倾子资料的定性分析解释提供了理论依据和指导. The two-dimensional forward modeling of the earth’s electromagnetic sounding method was used to simulate the model with transverse electrical interface under different conditions. The vertical component of the magnetic field was obtained and the real part, imaginary part, Amplitude and phase, and then analyzed the anomaly characteristics and regularities of the theoretical models under different conditions respectively.The results show that the dip data reflect the horizontal electrical interface existing in underground media obviously, but the different components The reflection characteristics and the reflecting ability of the transverse electric interface are different.Through the analysis and summary of the law of the characteristics of the leaning data in the theoretical model, it provides a theoretical basis and guidance for the qualitative analysis and explanation of the measured leaning data in the MT method .
