Engineering classification of jointed rock masses
TLDR
An engineering classification of jointed rock masses, termed the Geomechanics Classification, was proposed in this article, which is based on the Geodynamic properties of the jointed mass.Abstract:

Engineering classification of rock masses for the design of tunnel support
Nick Barton,R. Lien,J. Lunde +2 more
TL;DR: In this article, an analysis of some 200 tunnel case records has revealed a useful correlation between the amount and type of permanent support and the rock mass quality, with respect to tunnel stability.

Poisson's ratio values for rocks
TL;DR: In this paper, the effects of Poisson's ratio in the elastic deformation of materials, intact rocks, and rock masses are briefly reviewed, and the reported values of POI for some elements, materials, and minerals are compiled while typical ranges of values are presented for some rocks and granular soils.

Discontinuity spacings in rock
S.D. Priest,J.A. Hudson +1 more
TL;DR: In this paper, a relation between the Rock Quality Designation (RQD∗) and mean discontinuity frequency per metre (λ) was established: RQD ∗ = 100 e − 0.1λ (0.1 ε + 1).
