摘要
在长大隧道的勘察过程中,经常遇到多种特殊地质问题,如单纯采用传统的勘察方法,难以达到令人满意的效果。采用综合物探法,可以提供更准确、更全面的勘察报告,从而弥补常规地质勘察方法的不足。该文以某长大隧道勘察为例,采用音频大地电磁法、瞬变电磁法、钻孔测井法、孔内成像法等多种勘探方法,从多个侧面相互印证各自的物探异常特征,达到了误差小、精度高、可靠度高的目的,可为综合物探法在长大隧道的勘察提供参考。
During the survey of long tunnels,many special geological problems often occur.For example,it is difficult to achieve satisfactory results by simply using traditional survey methods.The comprehensive geophysical prospecting method can provide more accurate and comprehensive survey reports,thus making up for the defects of conventional geological survey methods.Taking the survey of a long tunnel as a case,this paper adopted a variety of exploration methods such as the audio magnetotelluric method,the transient electromagnetic method,the borehole logging method and the in-hole imaging method to verify the anomalous characteristics of geophysical exploration from multiple sides,which achieves the purpose of less error,high precision and strong reliability,providing reference for the comprehensive geophysical exploration method in the survey of long/large tunnels.
