| Abstract: | The tunnel gushing is a complex problem in tunnel engineering geology. Some problems, such as tun- nel gushing, soil flow, surrounding rock instability, etc. , may occur when the tunnel is being constructed, which will lead to problems such as project cost increasment, construction difficulty, seriously threatened con- struction personnel security and the extension of the time limit. In this paper, taking one tunnel on the Er＇guang Highway as an example, through the special hydro-geological investigation in the tunnel area, analyzed the hydro-geological conditions of the tunnel, determine the required supporting parameters for tunnel construction, provides guarantee for construction safety of tunnel engineering, so as to provide reference for similar tunnel design and construction. |
