摘要
该文采用音频大地电磁测深法,通过对2条剖面资料的处理与分析解释,与工程钻探资料进行了对比分析,查明了隧道开挖前方隐伏滑坡面的埋深及分布情况,为隧道的安全施工提供了可靠的科学依据。该工程实践表明,音频大地电磁测深法在隧道隐伏滑坡面勘察中是一种行之有效的物探方法。
In this paper by using the audio magnetotelluric sounding method,through the data processing,analysis and interpretation of two sections and the comparison with the engineering drilling data,the buried depth and distribution of the hidden landslide surface in front of the excavation of the tunnel are found out,which provides a reliable scientific basis for the safe of the tunnel construction.The engineering practice shows that the audio magnetotelluric sounding method is an effective geophysical prospecting method in the investigation of hidden landslide surface in tunnels.
