Stability Analysis of Underground Caverns by Jointed Finite Element Method

Abstract:

The jointed finite element method (JFEM) is used to analyze the deformation and failure characteristic of fractured rock mass and anchor reinforcement effect for the water collection shaft of the main power house of Dagangshan Hydropower Station. The results show that the JFEM not only simulates the actual rock mass structure very well, but also gives the reasonable simulation results for the common unstable rock mass. The JFEM may accurately simulate the major deformation characteristic and collapse mechanism, which is another effective way to analyze the stability of fractured rock mass. The on-site monitoring results show that the anchor reinforcement is effective for the water collection shaft
