PREDICTION OF UNIAXIAL COMPRESSIVE STRENGTH OF KIRANA HILLS DOLERITE BY ULTRASONIC PULSE WAVE VELOCITY

Abstract

This study was aimed at to explore the existence of any possible correlation between sonic wave velocity (VP) and uniaxial compressive strength (UCS) of dolerites of Kirana hills, situated in the province of Punjab, Pakistan. The experimental results were statistically analyzed using the method of least square regression to explore the existence of any correlation between VP and UCS. Three correlation equations having reasonably good R2 values were established and validated by an independent set of samples of the same rock. The majority of the computed values of UCS from the developed correlation equations were found to lie within acceptable statistical confidence limits.
