To better understand the interaction of parallel joints and its effect on the mechanical behavior of jointed rock mass models, the results of a physical experiment program undertaken in the laboratory were present in this manuscript. The joint spacing and joint overlap are varied to alter the relative positions of parallel joints in geometry. Accordingly, four basic failure modes identified from the...
•Red sandstone containing two unparallel fissures (new fissure geometry) was machined.•Analyze the effect of fissure angle α 2 on mechanical parameters of red sandstone.•Characterize cracking mode and charactertics of red sandstone by photographic monitoring.•Construct the relation between the stress-time curve and crack coalescence process, AEs.
