Webreduction from an intact rock to a rock mass, introduced by Hoek [12] in 1994. It is a unique rock mass classiﬁcation system used as part of the Hoek–Brown failure criterion for estimating the strength and stiffness of a rock mass [21,22]. Accurate estimation of the GSI is important for subsequent calculations [23,24]. WebThe rock mass contains two sets of joints controlling stability. These joints are undulating, rough and unweathered with very minor surface staining. RQD values range from 85% to 95% and laboratory tests on core samples of intact rock give an average uniaxial compressive strength of 170 MPa. matthew pullinger architect

Webon the rock mass and its stress and hydrologic characteristics, the use of a rock mass classification scheme can be of considerable benefit. At its simplest, this may involve using the classification scheme as a check-list to ensure that all relevant information has been considered.

The Geological Strength Index, in its original form, was not scale dependent, thus the block size is not directly related to the rock mass type.
