音频大地电磁测深法在喀斯特隧道中的应用研究

Research on Application of Audio Magnetotelluric Sounding Method in Karst Tunnel

通过音频大地电磁测深法进行野外勘探与研究,查明喀斯特隧道所造区域的地层、岩性分界线、地质构造特征,特别是破碎带、断层、软弱夹层宽度以及喀斯特溶洞、溶蚀裂隙、破碎软弱或富水岩体的埋深和规模,为隧道围岩类别划分提供参考依据。

Carry out field exploration and research through audio magnetotelluric sounding method to find out the strata,lithologic boundaries and geological structural characteristics of the area created by karst tunnel,especially the width of fracture zone,fault and weak interlayer,as well as the buried depth and scale of karst cave,dissolution fissure,broken weak or water rich rock mass,so as to provide reference basis for the classification of tunnel surrounding rock.
