中文摘要 | 音頻大地電磁法為一種頻率域的電磁探勘技術,係應用不同頻率(1k Hz ~69.5k Hz)的電磁波入射地下,地下深度不同的各地層因孔隙率、裂隙、岩性及 構造等差異,導致地表接收不同之電磁感應,以此來區分各地層含水特性。本研 究於屏東縣興華農場應用音頻大地電磁法進行該區之地下水水位與地下水流向 調查,調查結果與事後鑽井觀測成果吻合,證明音頻大地電磁法為一有效、快速 且成本較低的非破壞方法。 |
英文摘要 | The audio-frequency magnetotelurics (AMT) method is a frequency domain exploration technique. It is based on the electromagnetic (EM) responses of layers at different depth from an incident of natural (EM) waves with frequencies in the range from 1k Hz to 69.5k Hz. Layers characterized by different porosity, lithology, fracture and structure etc. have different types of induced EM responses on the surface. Therefore, the hydraulic properties of layers can be figured out. This paper reports an investigation of groundwater table and flow in the Hsing-Hwa farm, Pingtung by using an AMT survey. The final results were verified by post drillings, this non-invasion technique has many advantages - economic, surveying fast and result reliable. |
