Study on the Wall Rock Stability of Yantan Hydrologic Station’s Underground Caverns by Using 3D Numerical
Based on the simplified structure of rock mass, FLAC3D numerical modeling technique is used to systematically analyze the distribution features of the secondary stress field, strain field and plastic zones in the surrounding rock mass of the underground cavities after the excavation. And the variation characteristics of stress field, strain field and plastic failure zones in the surrounding rock mass of the underground cavities are summarized. The results show that the underground workshop building caverns are whole stable, but parts of them are unstable and the unstable parts are shallow. The results provide basic information and reference for the evaluation of underground cavities stability and project construction.
