In recent years, there has been an increasing interest internationally in the construction of large-scale underground powerhouses. The stability analysis of underground caverns in a hydropower station is often related to the safe operation of the whole station and provides enormous benefits. Due to their large scale, complicated space configurations and reactions between caverns, stability analysis of underground powerhouses is a very difficult and challenging task. Hence, the accurate description of the mechanical behavior of the rock mass and the selection of the rock properties is a very important research topic in underground construction.
