Characterization of rock material by point load strength index test and direct cut
Minerva, 2021 The objective of this work is to establish a relationship between the cutting time in rocks, determining a speed and the point load strength index test, Is (50), to characterize the rock in terms of resistance and avoid sending samples to laboratories. As a first stage, on andesite samples, 5 x 5 x 10 cm test tubes were made. After the elaboration they

The use of point load test for Dubai weak calcareous sandstones
Journal of Rock Mechanics and Geotechnical Engineering, 2015 Intact rock is typically described according to its uniaxial compressive strength (UCS). The UCS is needed in the design of geotechnical engineering problems including stability of rock slopes and design of shallow and deep foundations resting on and/or ...

A new index combining weak layer and slab properties for snow instability prediction [PDF]
Natural Hazards and Earth System Sciences, 2015 Snow slope stability evaluation requires considering weak layer as well as slab properties – and in particular their interaction. We developed a stability index from snow micro-penetrometer (SMP) measurements and compared it to 129 concurrent point ...
