Abstract：The Nanshibi Tunnel in Jiangxi province is located in the karst development zone. During the operation period, the water gushing and mud gushing diseases occur every time of seasonal heavy rainfall. The water gushing points are scattered and the water gushing volume is large, which cannot be completely solved by many treatments. Accurate positioning of water source and water guiding channel is the premise of disease control. The integrated detection method was used to detect before the grouting treatment. The water body was located by transient electromagnetic and high-density electric method, and the cave and fault-breaking area were detected by seismic mapping method. The comprehensive geophysical prospecting results were compared and analyzed to determine the spatial location and distribution pattern of the unfavorable geological bodies. The correctness of geophysical prospecting results was verified by the exposure of left hole drilling and grouting line. The research results show that: for operating tunnels in karst areas, the comprehensive use of multiple geophysical prospecting technologies and their mutual confirmation can accurately locate the spatial distribution of water-filled karst caves and water-conducting fissures, which is of guiding significance for the tunnel disease treatment construction.
