Question

How to derive rockmass properties from intact rocks properties?

Answer 1

Explanation:

determine the uniaxial compressive strength ci The strength of a jointed rock mass depends on the properties of the intact rock pieces.

Answer 2

Explanation:

Discontinuities make the rock mass weaker, with higher permeability. We combine what we learn from the intact rock through laboratory tests with the pattern of discontinuities (e.g., number of discontinuity sets, spacing, and orientation) and come up with the big picture that is the rock mass.
