[ 1 ] - Reliability assessment of Needle Penetration Index for estimating compressive strength of some sedimentary rocks from the Qom Formation, Central Iran
In this paper, the needle penetrometer test was utilized to explore the reliability of the Needle Penetration Index (NPI) for estimating the Unconfined Compressive Strength (UCS) of sedimentary rocks including gypsum, marl, siltstone and sandstone collected from the Qom Formation. Following the UCS and NP test, regression analyses were carried out to control the predictive performances of NPI. ...
