Correlation between Uniaxial Compressive Strength and

2008-6-6 · The dependence of the UCS versus Is(50) correlation on rock types was demonstrated by Cargill and Shakoor [11]. They found the following correlation equation: qu = 13 + 23 Is(50) Chau and Wong [12] proposed a simple analytical formula for the calculation of the UCS based on corrected Is to a specimen diameter of 50 mm Is(50).
