根据海冰、内陆湖泊、河流、冰川等冰资源与环境中的自然科学问题及冬季结冰地区水工结构物安全运行管理中对冰层厚度时空变化资料的需求,基于电磁场的特有性质,讨论了可用于冰层厚度检测的两种电磁探测方法-时间域电磁法和频率域电磁法,较详细讨论了它们的工作原理、研究进展、适用范围和在冰层厚度检测中获得的初步应用结果,并通过对实际测量结果的分析比较,提出了频率域电磁法,相对于时间域电磁法,在冰层厚度检测中具有更多的优势.
According to the natural sciences in ice resources and environment such as sea ice, inland lakes, rivers and glaciers, and the demand for the temporal and spatial variation of ice thickness in the safe operation and management of hydraulic structures in icing regions in winter, based on the unique properties of electromagnetic fields, Two kinds of electromagnetic detection methods which can be used for the ice thickness measurement are discussed-time domain electromagnetic method and frequency domain electromagnetic method. Their working principle, research progress, application scope and preliminary application in ice thickness measurement are discussed in detail. The results show that the frequency domain electromagnetic method is proposed by comparing with the actual measurement results. Compared with the time domain electromagnetic method, it has more advantages in the ice thickness detection.
