Application of High-Power Electrical Sounding 3D Imaging Technology in Tunnel Geological Prediction

In actual tunnel engineering, there are few ideal geological conditions, and the always cuts through areas with high incidence of disasters, which increases difficulty construction. this paper, taking special survey work comprehensive geophysical exploration a in unfavorable conditions as an example, we carried out prediction by high-power electrical sounding 3D imaging technology. The results indicated that was mainly structural fracture zone bountiful water, where such collapse, water inrush, mud burst gushing, occurred easily during construction, were 4 serious sections less DK0+180–DK0+760 tunnel. Thus, effective engineering measures should be taken to ensure safety reliable, providing basic data reference for future prediction.
