Complicated geological conditions and high level ground stress are often encountered with challenges in the construction of underground caverns. It is a key problem to ensure the stability of surrounding rock during construction and operation. The numerical method can be used to simulate and predict the actual situation, to evaluate the feasibility and safety of the excavation and reinforcement scheme, and to provide the optimization suggestion and reduce the engineering risk. An underground pumping station of a water diversion project as a case study, using numerical inversion of in-situ stress, and analysis plastic volume and key points of displacement are conducted and compared under the supporting and no supporting cases, predicting the rock stability during the excavation process and providing some suggestions respectively for engineering design.
