The stability evaluation of the Jurong underground powerhouse complex, which is a part of a pumped storage power station, is conducted in this paper. The appropriate calculation method has been selected based on the dominant mechanism of rock failure. The failure of rock mass in this project is mainly controlled by the discontinuity distribution because of the level in situ stress and rock mass quality. The use of Discrete Fracture Network (DFN) model has become an important tool in rock mechanics works design. With the help of the Distinct Element Method (DEM) software 3DEC, the DFN model is realized and the instable blocks of the complex are exposed, some construction suggestions have also been provided considering instable blocks.
