摘要

多辐射场源半航空瞬变电磁法是对电性源半航空瞬变电磁法的发展和补充,具有探测深度大、地形适应性强和工作效率高的优点。基于一维正演理论,本文对平行辐射场源、带角度多辐射场源和单个源模型在空中产生的三分量瞬变响应特征进行分析,结果表明:整体来说z分量瞬变响应曲线形态最为简单,多辐射场源情况下响应增强的特点最明显,最利于数据处理和解释;x分量瞬变响应形态最为复杂,在全场域经常表现出极性反转的变号现象,但晚期信号幅值总是增大;y分量瞬变响应受电流方向和接收点位置的影响最大,曲线形态和响应幅值变化均较为复杂。结合偏移距变化下响应衰减幅度,建议工作区域偏移距控制在辐射源长度的5~6倍内为宜。本文的研究结果可为实际勘查工作的野外施工布置及定性分析提供参考,同时获得了对该方法的初步认识。

Abstract：

Multi-source semi-airborne TEM is a supplement and development of electric source semi-airborne TEM. It has characteristics of great detective depth, strong adaptability in complex topography and high working efficiency. Based on the one-dimensional forward algorithm, the author analyzed the full-component response of parallel source and multi-source and single-source models. The results show that the curve of vertical component z is the simplest and it can be significantly strengthened with multi-source, which means this component is the most suitable one for data processing and interpretation. The most complex component is x. The curve always shows sign-changing in full field, but the magnitude can be strengthened in late stage. As the horizontal component y is most affected by current direction and receiver location, the curve shape and magnitude change are both complicated. Combined with the response characteristics of magnitude variation versus offset, it is suggested that the working area should be within the range of 5~6 times of source length. The research results in this paper can provide a reference for technical support to its application and obtain a preliminary understanding of the method.

Key words： multi-source electric source semi-airborne transient electromagnetic method three-component response
