Excerpt

From the earliest studies on the topic, plane sliding techniques, usually known as tilt tests, have shown contradictory features. On the one hand, they reflect on a small-scale basic principles regarding definition of the friction angle and can reproduce conditions very similar to those of the sliding of blocks on rock slopes; furthermore, tilt angle results agree with friction angles derived from shear and pull tests (Hencher 1977; Muralha 1996). On the other hand, the literature includes several reports of erratic results and it is recognized that even apparently smooth surfaces are actually rough at the microscopic level (Hencher and Richards 2015). Thus, adhesion and textural interlocking may contribute to the variability and the non-reproducibility of tilt test results. …
