EH-4 electromagnetic imaging systems to detect the accumulation of body applied research

本文简要介绍EH-4电磁成像系统的基本原理与工作方法,论证了该方法在探测堆积体方面的有效性,阐明了该系统对高阻厚层和低阻薄层勘察的相对灵敏性。然后对云南古水水电站三个堆积体的电性特征及EH-4电磁成像系统勘查的有效性进行了分析,并对观测数据进行了处理和研究,展示了该方法在探测堆积体规模、厚度、形态和与基岩界面方面的应用成果,最终得出了一些有意义的结论,供同类工程参考。

In this paper, the author introduces the basic principles and methods of work of EH-4 electromagnetic imaging system. Firstly, the author provides the method to detect the accumulation of survey in the effectiveness; then explains that EH-4 electromagnetic imaging system has relative high resistance thick layer and low resistance thin layer sensitiveness. Through EH-4 electromagnetic observation data processing and analysis studies in the three accumulation of hydropower stations in Yunnan, it shows that the method in detecting the accumulation of body size, thickness, shape and boundary with the bedrock of has successful application. Finally, some meaningful conclusions have been drawn up.
