Abstract Research purposes: The water bursting and mud bursting are the common appearances encountered in tunnel construction and they can produce the big harm to the construction. The Maluqing Tunnel is one of eight tunnels with Grade 1 Risk. There are lots of the unfavorable geological conditions, such as the underground hidden river, karst, high pressure, rich water and karst cavity. The large water bursting and mud bursting happened many times in the construction. Based on the research on the water bursting and mud bursting happened to this tunnel, this paper analyzes the various influence factors on the water bursting and mud bursting and discusses the control of the water bursting and mud bursting of the tunnel.
Research conclusions: From the analysis it is concluded: (1) The water bursting of the karst tunnel relates closely to the storage volume and water pressure of the static water in the karst cavity and to the connectivity of the underground water system. (2) When the tunnel pass the high-pressure and rich-water karst stratum, the advanced geological forecast work should be well done. It is recommended to use the advanced horizontal drilling method along with the peripheral drilling method for clearly exploring the engineering geology, the features of hydrogeology and the boundary condition of the karst cavity, and the reliable engineering measures should be taken in advance to ensure the construction safety, the structure stability and the operation safety.
