Whereas, the thickness of the gouge as large as 2 mm does not seem to influence the sliding stability, even though the gouge thickness will significantly weaken the frictional strength of basalt fracture. The results suggested that the evolution of basalt fracture...

The stress–strain output, peak stress, and peak strain were summarized, and the relationship between the peak stress and temperature was obtained based on the experimental data. The results of the test show that high temperatures can weaken the mechanical properties of granite...
