With the rapid development of my country's economy and society and the continuous implementation of various large-scale construction projects,the number of large-scale deep-buried underground tunnel construction projects has increased.The geological conditions of the projects are complex and diverse,and they often face a varie-ty of extremely unfavorable geological conditions.Xianglushan Tunnel is a deep-buried long tunnel with geological conditions,known as the"Geological Museum".Water and mud burst often occur.During the construction,water and mud burst occurred in the main tunnel upstream of the 3 # branch tunnel.By analyzing the geological and hydrological conditions of the water and mud burst section,the surface interception and interconnection test were used to find the groundwater recharge source in the tunnel water and mud burst area.Combined with the surround-ing rock characteristics of the tunnel water and mud burst section,the concrete plug in the tunnel was reasonably set,and drainage and pressure relief measures were taken to successfully deal with the water and mud burst and a-void the expansion of the disaster.
