Abstract

Abstract:

In this paper, the geological conditions and rockbust course of serious rock burst section of AngrenPop railway tunnel in Uzbekistan are described in detail. The causes of rock bust are analyzed in terms of rockburst conditions and geological conditions. The countermeasures for rock bust are presented. In the end, the safety of the construction of serious rock burst section has been guaranteed.

Key words: railway tunnel, serious rock burst, reinforcement, bench method, monitoring
