Abstract
A practical procedure for estimating the deformation modulus of rock mass from Bieniawski's rock mass rating (RMR) is proposed. The procedure is based on the Hoek-Brown failure criterion and the fact that the critical strain of rock mass is approximately as the same as one of the intact rock. Thus the deformation modulus of rock mass is expressed in terms of the elastic modulus of intact rock multiplied by a reduction factor which is a function of RMR. The comparison of the proposed and the existing procedures with the results obtained from plate loading test shows that the proposed one improves the estimation of deformation modulus of rock mass.
