STRENGTH PROPERTIES OF ROCKS AND ROCK MASSES 1

In general rock mass strength depends on the strength of intact rock and the strength of rock discontinuities In general compared to intact rock a rock mass has reduced tensile strength almost zero and reduced shear strength especi ally along discontinuity planes Furthermore if a rock mass is cut by directional joint sets the rock

One of the most common ways of estimating the rock mass strength is by using a failure criterion The existing rock mass failure criteria are stress dependent and often include one or several parameters that describe the rock mass properties These parameters are often based on classification or characterisation systems
