Compared to other basic mechanical properties of rocks, Poisson’s ratio is an elastic constant of which the significance is generally Q\th8/ /
underrated. Yet, in rock mechanics, there is a considerable number of diverse areas which require a prior knowledge or estimation of the "r(pK@h
value of Poisson’s ratio. This paper examines the values and applications of Poisson’s ratio in rock mechanics. Following an historical 'm.XmVZL%
account of the initial controversy, whether it was a material constant or not, the effects of Poisson’s ratio in the elastic deformation of p!5JO4F$
materials, intact rocks, and rock masses are briefly reviewed. Also, the reported values of Poisson’s ratio for some elements, materials, 2SCf]&
and minerals are compiled while typical ranges of values are presented for some rocks and granular soils. Finally, Poisson’s ratio OKH~Y-%<
classifications are recommended for isotropic intact rocks.
