Abstract :
Based on the simplified structure of rock mass, FLAC3D numerical modeling technique is used to analyze systematically the distribution features of filed, strain field and plastic zone in the surrounding rock mass of the underground cavities after the excavation. And, the variable regulations of stress filed, strain field and plastic failure zones in the surrounding rock mass of the underground cavities are summarized. The main results can be taken as the basic data and the theoretical proofs to evaluate cavities stability and guide the correct excavation.
