Abstract: This paper presents the development of the empirical relationship between the point load test results and the unconfined compressive strength of intact rock samples of hard sandstone sample of Murree Formation of Tertiary Period in Pakistan NeelumJhelum (NJ) Hydropower Station Project. Throughout the regression analysis of test results, two different empirical relationships, linear relationship and index relationship, were developed. The point load test results could be used in the prediction of the unconfined compressive strength of intact rock samples. The compressive strength of intact rock can be used in the rock mass quality classification.

Key words: Point Load Test, Unconfined Compressive Strength, Conversion Coefficient, Empirical Relationship
