摘　　要：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.Based on the requirement of the ice thickness change, in the natural science space and time, about the resources and environments of lake, river, sea and glacier ices and in the engineering science, the structures safe operation of the ice infested waters in winter, the paper advances two electromagnetic methods of the ice thickness measurements. The two methods include Time-Domain Electromagnetic methods and Frequency- Domain Electromagnetic methods. This paper introduces their work principle, the research advances, the useful case of ice conditions and the preliminary results from the practice in the ice thickness measure. Through the an.alysis of the actual practice results, Paper points out more advantages of Frequency-Domain electromagnetic methods over Time-domain electromagnetic methods in the matter of ice thickness measurements.
