摘要
该文介绍了可控音频电磁法(CSAMT)和高密度电法相结合,应用于四川雅安至石棉段高速公路的大相岭隧道构造、岩性的勘察实例。通过与钻探及地质调绘的资料对比,可以说明CSAMT法和高密度电法相结合,可以在宏观上查明深埋隧道地层岩性、地质构造及其赋水性,为钻孔布置及隧道设计、施工提供地球物理依据,在深埋长隧道勘查中能起到理想的运用效果。
Combined CSAMT with high density resistivity method , the paper introduces an exploration example for the structure and lithology in bedrock of Daxiangling tunnel. By comparing with the data of borehole and engineering geological mapping, the combination of CSAMT with high density resistivity method can macmscopically get the stratum lithology, the geological structure and water saturation of deep-buried tunnel and provide useful information for selecting borehole location and tunnel design and construction. It can achieve ideal effect in exploration of deepuffed long tunnel.
