PREDICTION OF UNCONFINED COMPRESSIVE STRENGTH OF ROCKS BY POINT LOAD STRENGTH INDEX [PDF]
Journal of Al-Azhar University Engineering Sector, 2019 The point load testing is widely used to determine rock strength indeces in geotechnicalpractices as a result to simplicity. The present study presents correlation equations betweenthe unconfined compressive strength (qu) and point load strength index Is(50) adopted fordifferent types of rocks.

Minerals, 2021 Uniaxial compression strength (UCS) is a fundamental parameter to carry out geotechnical engineering design and construction. It is simple and efficient to predict UCS using point load strength (PLS) at engineering sites. However, the high dispersion of rock strength limits the accuracy of traditional fitting prediction methods. In order to improve the

Correlation between Uniaxial Compressive Strength and Point Load Strength of Penang Island Granites
IOP Conference Series: Earth and Environmental Science, 2022 Abstract Uniaxial compressive strength (UCS) is one of the most widely used strength parameters in geotechnical design. The value is obtained through direct testing method, carried out through careful procedures of testing in a laboratory setting. As such, it is relatively more expensive, more tedious and requires longer time to complete.
