Estimation of the uniaxial compressive strength (UCS) of rock has been an unavoidable topic among geotechnical engineers dealing with rock and rock mass for the last couple of decades. A considerable number of models and empirical equations have been proposed to estimate the UCS of rocks as mentioned in the technical note by Jamshidi et al. (2018). However, each equation has a limited performance capacity that depends on the rock types and the available data.
In the paper of interest here, 18 different types of limestones are considered, i.e., commonly fossiliferous limestones of sedimentary origin which belong to the Asmari formation in Iran. Therefore, the rock tested may show a different behavior under loading due to variation of the degree of weathering, although the origin and rock type remain the same.
One of the most crucial issues is that the use of correct data and estimation approaches is needed to obtain a reliable output. This paper gives some suggestions and comments on...
