瞬变电磁法在内蒙古乌拉特前旗明安镇西找水工程中的应用

内蒙古自治区乌拉特前旗明安镇西某农业开发区需建设水井若干,地下水分布受隐伏断层影响而阻断,利用中心回线瞬变电磁法,布置了5条测线,准确定位出隐伏断层位置。通过自主开发的解释程序,实现了人机交互的定量解释:不仅推断出含水地层厚度倾向、断层产状,划定含水层区域范围,有效避免了干井的出现,而且为野外数据的快速定量解释提供了新的技术手段。

The Application of TEM in Water Exploration of The West of Ming

There are several water wells to be built in the West Agricultural Development Zone of Ming''an Town, Wulateqian Banner, Inner Mongolia Autonomous Region.The groundwater distribution was blocked by a buried fault.By using the Central loop TEM ,the fault location was accurately found in five prospecting survy lines. Through the self-developed interpretation program, the quantitative interpretation of human-computer interaction is realized: not only can the thickness, tendency and fault occurrence of formation be inferred, but also the regional scope of aquifer be delineated, which effectively avoids the emergence of dry wells, and provides a new technical means for rapid quantitative interpretation of field data.
