频率电磁测深法频率电磁测深法frequency electro-magnetic soundingP inlud一onCi eeshen fa频率电磁测深法(frequeney eleetr。一mag-netie sounding)观测、研究不同频率的脉冲交变电源激励地下介质产生的瞬变电磁场分布规律和衰减特性的工程电法勘探方法。该方法应用电磁感应的趋肤效应,由高到低地改变工作频率,以达到由浅入深地探测地质目标的目的。此法可用来进行地层分层,探测岩溶发育带、断层破碎带、软弱泥化夹层和滑坡面等。频率电磁测深法一般采用固定极距的赤道偶极装置,用双边赤道偶极装置可提高工作效率。观测方法是按预定的工作频率(频点)由高到低地通过供电偶极AB向地下供电,测量相应频点的供电电流I,在接收端分别测量偶极MN和测量线圈相应频点的电位差△VEx和磁场感应电动势△VB:,并计算电场和磁场的振幅值府和沸。频率电磁测深法一般选用8一12个频点,若用它做剖面选用2一3个频点。该方法研究的是电场和磁场的振幅和相位,因此可相应得到反映电场振幅、磁场振幅、电场相位和磁场相位4条曲线丙、沸、六和内。资料解释分定性和定量解释,常用的定量解释方法有量板法和平均纵向电阻率法。时间域技术是频率电磁测深法的发展方向,可提高解决地质问题的能力和解释精度。但该方法的探测深度一般大于20m,影响其在工程勘察中应用。频率电磁测深仪一般由电源、控制、发射和接收四部分组成。按方法体制可分为频率域和时间域电磁测深仪两大类。(范昌隆)
