Failure Process and Stability Analysis of Rock Blocks in

Finally, the safety factor of each block is calculated via the strength reduction method SRM. For an underground powerhouse project that is crossed by a fault, the stability of the block and the surrounding rock were analyzed. The research results can provide effective references for the block stability under complex geological conditions. 2.
