| Abstract: | Guan Jiao tunnel is the longest railway tunnel built in our country at present. During the construction,such geological problems as water burst,soft and broken surrounding rock deformation are encountered. This article focuses on the main geological problems encountered in the construction of Guanjiao tunnel to conduct cause analysis,summarize the types and characteristics of super long tunnel construction geological problems,identify the mechanism of such problems so as to improve the ability to deal with the geological problems,promote the practices in copying with complex geological problems and improve technological levels. |
