Scale Effect and Correlation between Uniaxial Compressive Strength and Point Load Index for Limestone and Travertine [PDF]
Applied Sciences (Switzerland), 2021 Determining the uniaxial compressive strength of intact rock is the primary objective of a geomechanical project, and a reliable estimate in the early phases saves time and costs for more sophisticated laboratory tests. The problem is knowing which of the correlations between the resistance to uniaxial compression and point load index are reliable ...

A new method for evaluating the rock mass damage index based on the field point load strength [PDF]
Royal Society Open Science, 2019 The damage index is a crucial controlling parameter for rock mass strength and deformation in civil, geological and mining engineering projects. In this study, a new method was proposed for computing the damage index of a rock mass based on the field point load strength.
