英文摘要	For analysis and regulation of large underground caverns by a quick way, a new failure mode classification method for surrounding rock of large-scale cavern group is proposed. Based on the three levels, "control factors" double right arrow "failure mechanism" double right arrow "generation conditions", 18 typical failure modes have been summarised. The corresponding stability analysis methods and control measures are recommended for each failure mode. Furthermore, a new method is also proposed for dynamic recognition of failure modes and the corresponding control measures according to dynamic updating of geological conditions and characteristics of surrounding rock revealed during excavation. The new methods have been applied to the large-scale cavern group of Jinping II hydropower station successfully.
