Abstract：The three-dimensional network distributed electromagnetic exploration system(Geode EM3D),as an advanced geophysical exploration technology,plays a significant role in tunnel geological surveys.This study outlines the basic principles and working mechanisms of Geode EM3D and describes its application process in hydraulic tunnels under complex geological conditions using an actual engineering case.The results show that this technology can effectively and accurately identify adverse geological sections in tunnels,such as faults,fractured zones,and karst development areas,providing detailed information on their location,scale,and type.It can promptly detect potential geological hazard risks,ensuring the safety of geological surveys and construction for hydraulic tunnels while significantly improving construction efficiency.This technology provides crucial technical support for safe tunnel construction and geological disaster prevention.
