摘　　要：断层是影响隧道稳定的不良地质现象,EH4电磁测深法工作频率在10 Hz～100 kHz,其探测深度大,本文应用EH4电磁测深法探测埋深不同的隧道,断层勘察效果较好,探明了断层的宽度、倾向、倾角等地质要素,其探测结果可指导隧道设计并对开挖过程中的灾害进行预防和提前处理。The fault is affecting the stability of the tunnel adverse geological phenomena, EH4 e- lectromagnetic sounding method operating frequency of 10 Hz - 100 kHz, probing depth, In this paper,EH4 electromagnetic sounding method to detect the depth of different tunnel, better fauh investigation proved the fault width, orientation, inclination, and other geological elements, the detection results can guide the disaster in the tunnel design and excavation process for prevention and early treatment.
