摘　　要：随着我国铁路网的不断扩展,在高原及艰险山区构建铁路网已成必然。然而,因地势陡峭,部分线位人员无法抵达,常导致关键勘察数据缺失。为解决这一问题,从传统地面勘察转向空中,采用地球物理技术与无人机技术相结合的半航空频率域电磁法。针对高原艰险山区长大深埋隧道的勘察需求,团队自主设计研发了半航空电磁硬件系统,通过与地面方法的同精度对比验证,其结果一致性达到90%以上。该技术成功应用于某隧道测区的勘察任务,弥补了因地势陡峭导致的勘察数据空白,有效降低了勘察成本,显著提高了工作效率,为我国铁路勘察工作提供了新的技术路径与方法。As China s railway network continues to expand,constructing railways in plateau regions and rugged mountainous areas has become a necessity.However,due to steep terrain,certain sections remain inaccessible to field personnel,resulting in gaps in critical survey data.To address this challenge,a shift from traditional ground surveying to aerial surveying has been made.A semi-aerial frequency-domain electromagnetic(FEM)method that combines geophysical technology with drone technology was employed.In response to the demand for surveying long,deeply-buried tunnels in these challenging terrains,we independently designed and developed a semi-aerial electromagnetic hardware system.When compared with ground-based methods,the system demonstrated a consistency exceeding 90%.This technology has been successfully applied in the survey of a specific tunnel area,filling in the data gaps caused by steep terrain.The method significantly reduces survey costs,enhances operational efficiency,and offers a novel technological pathway for railway surveying in China.
