| Abstract: | Three-dimensional finite element numerical modeling technique is used to analyze systematically the distribution of stress filed, strain field and plastic zone in the surrounding rock mass of the underground cavities after excavation. And, the spatial variance of stress, strain 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 correct excavation. |
