摘要:
本文介绍了无人机地空时频电磁物探的基本工作原理,并将该方法应用于西渝高速铁路天坪梁隧道勘察中。为验证无人机地空时频电磁物探成果的准确性,采用了地面大地电磁物探(EH4)方法和地质钻探方法进行了验证。研究结果表明:(1)无人机地空时频电磁物探具备较好的可靠性及准确性,能够较好地反映地下电性结构,有效地探测地下各类地质体;(2)无人机地空时频电磁物探不受地形、地貌限制,具有效率高、成本低的特点,值得在复杂艰险山区铁路隧道勘察中推广。研究成果可为隧道勘察设计提供参考借鉴。
Abstract:
This paper introduces the basic working principle of UAV-based ground-air time-frequency electromagnetic geophysical prospecting,and the application of this method in the investigation of Tianpingliang Tunnel of Xi’an-Chongqing High-speed Railway. In order to verify the accuracy of the results of UAV-based ground-air time-frequency electromagnetic geophysical prospecting,the surface magnetotelluric geophysical prospecting (EH4)and the geological prospecting were used for verification. The results of the study show that:(1)The UAV-based ground-air time-frequency electromagnetic geophysical prospecting has good reliability and accuracy,and can better reflect the underground electrical structures and effectively detect various underground geological bodies. (2)The UAV-based ground-air time-frequency electromagnetic geophysical prospecting is not limited by terrain or landform,and has the characteristics of high efficiency and low cost,worthy of being popularized in the investigation of railway tunnels in complex and dangerous mountainous areas. The findings of this paper can provide reference for tunnel survey and design.
