samples are water saturated, the bulk modulus of the rock is frequency dependent. Modeling with Gassmann’s equations predicts the measured saturated rock bulk modulus for all fluids for frequencies below 20 Hz but underpredicts the water-saturated basalt bulk modulus for frequencies greater than 20 Hz. The most likely reason is that the pore ...

Values of tensile and cohesive strength for the basaltic rock mass are approximately one to two orders of magnitude lower than corresponding values for intact basalt. Temperatures comparable to those at the Venus surface may slightly increase the deformation modulus but decrease the compressive strength of the rock mass.

deformation modulus of rock masses was made by Hoek and Diederichs (2006). This chapter presents the most recent version of the Hoek-Brown criterion in a form that has been found practical in the field and that appears to provide the most reliable set of results for use as input for methods of analysis in current use in rock engineering.

Feb 13, 2015 Poisson’s Ratio of Rock. Poisson’s ratio measures the ratio of lateral strain to axial strain at linearly elastic region. For most rocks, the value of Poisson’s ratio ranges in between 0.15 to 0.40. Typical values of modulus of elasticity of some common are given in the table below.

A study of strength and deformation measurements for basaltic rocks, along with consideration of the influence of fracturing using a rock mass classification system, documents the range of brittle response for basaltic rock masses. Although basalts vary widely in composition and other physical factors, many of the properties of a basaltic rock mass appear to vary within a factor

The Biot coefficient is only defined for the bulk modulus because it is the ratio of pore-volume change to total bulk-volume change under dry or drained conditions.

Basalt, extrusive igneous (volcanic) rock that is low in silica content, dark in color, and comparatively rich in iron and magnesium. Basalts may be broadly classified on a chemical and petrographic basis into two main groups: the tholeiitic and the alkali basalts. Learn more about basalt in this article.
