Failure Process and Stability Analysis of Rock Blocks in a Large Underground Excavation Based on a Numerical Method
A numerical analysis method for block failure is proposed that is based on continuum mechanics. First, a mesh model that includes marked blocks was established based on the grid-based block identification method. Then, expressions of the contact force under various contact states were derived based...
