Abstract：In this stability analysis of underground caverns，influencing factors，such as mechanical parameters of surrounding rock masses and height，depth and spacing of caverns and so on，are considered. This paper performs numerical simulations of 16 operating modes，and establishes a model of the analytic hierarchy process of stability analysis for large-scale underground caverns. The process includes construction of decision matrices，solution of characteristic vector and verification of consistency. The method can be used in general sequencing for influencing factors of the stability of surrounding rock masses and provide a basis for the stability forecasting of underground caverns.
