Reliability and evaluation of point load index values obtained from different testing devices [PDF]
Journal of the Southern African Institute of Mining and Metallurgy, 2020 In some rock mass classification methods, the point load index (PLI) value is used as a parameter in the determination of the class of rock mass. The PLI value may be used as a design parameter such as uniaxial compressive strength (UCS) and tensile strength (TS), owing to its being simpler, faster, and cheaper and easier to prepare than the specimens ...

Periodica Polytechnica Civil EngineeringPoint load test is a common, inexpensive and fast test for the indirect achievement of compressive or tensile strength of the rocks in the laboratory and the field. In this research, by conducting uniaxial compression test (UCT), axial (APLT), and diametral (DPLT) point load tests on gathered sulfate rock blocks from the Gachsaran Formation outcrops at

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

OPTIMAL LOAD SHEDDING BASED ON LINE VOLTAGE STABILITY INDEX USING HARMONY SEARCH ALGORITHM [PDF]
Journal of Engineering Science and Technology, 2015 Modern power systems have been operated close to their limits for reasons of economic viability. Consequently, a small increase in the load may lead to the Maximum Loading Point (MLP) of the system resulting in voltage collapse. Under such circumstances,

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 ...
