Abstract Geological hazards like water inflow and mud bursts often occur during tunnel construction in water-rich geology, and these are detrimental to safe construction. Engineering practice indicates that single advance geological prediction may lead to erroneous judgment. Based on the geological conditions of the Tongluoshan tunnel, a comprehensive geological prediction technology was proposed concerning water bursts, namely, giving full play to the advantages of the TRT method, transient electromagnetic method, and advance horizontal drilling. The results show that this comprehensive technology provides an effective geological reference for construction decisions, to some extent preventing the tunnel from geological hazards.
