Application of Schmidt rebound number for estimating rock strength under specific geological conditions

S. R. Torabi; M. Ataei; M. Javanshir

Volume 1, Number 2 , July 2010


  A literature review revealed that most of the empirical equations introduced for determination of the uniaxial compressive strength (UCS) of rocks based on the Schmidt hammer rebound number (N) are not sufficiently reliable mostly due to the relatively low coefficient of correlations. This is ...  Read More
