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。
Abstract:
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.
