摘要
Abstract
The characteristics of in-situ stress field are very important to the construction of pumped storage power station.In this paper,the hydraulic fracturing method is used to measure the in-situ stress of the underground powerhouse of a pumped storage power station,and the characteristics and stability of the in-situ stress field are systematically analyzed.The results show that the underground powerhouse area of the pumped storage power station is in the medium stress zone environment,the maximum horizontal principal stress direction is NW,and the surrounding rock at the buried depth of the underground powerhouse may have rock burst phenomenon.The research results provide corresponding data support for the prediction of rock burst and the arrangement of tunnel axis.关键词
