Analysis of Surrounding Rock Stability of Underground Nuclear Power Plant Caverns

Considering the characteristics of the underground nuclear power Caverns, the stability of the surrounding rocks in the excavation and earthquake is analyzed by the methods of project survey, comparison and numerical calculation. The results show that we have the experience of same size project as the underground nuclear power caverns in the underground project practice in China; and the nuclear power cavities are with strong seismic capacity. The safety and stability of the underground nuclear power caverns can be effectively guaranteed by the site selection, rational layout and suitable supporting.
