Socketing of Bored Piles in Rock 680 Based on Shear Strength of Parameters of Rock Shear stress of rock (τ) is a fraction of its unconfined compression strength (τc). τ may be taken either as a linear fraction of τc with coefficients ranging from to or as a fraction of square root of τc with coefficients ranging from to ...

what is the rock mass strength. Knowledge of roc k mass strength is also important in the design of support systems as discussed in the next set of notes with regard to the concept of rocksupport interaction. In general, rock mass strength depends on the strength of intact rock and the strength of rock discontinuities.

The HoekBrown strength criterion was applied to estimate the strength of the rock mass at the Aznalcollar open pit. It was shown that by assuming disturbed rock mass, a good agreement was found between estimated strength values and backcalculated strengths from observed slope failures in the footwall. These values are probably conservative and
