The estimation of rock mass deformation modulus using ...

Rock mass deformation modulus (EM) is an important input parameter in geomechanical problems. Field tests to determine this parameter are time consuming and expensive. In this paper, two methods have been developed to estimate EM. In the first method, using regression analysis, five empirical equations have been obtained relating EM and the ...

Compressive strength of rocks - PetroWiki

Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or sonic velocities, but …

Thus, only presumptive values of the constrained modulus (Ms) for crushed rock are available. As discussed in a companion paper (Gemperline and Gemperline 2011), a large-scale confined modulus laboratory test was developed to quantify M s values for gravel size particles. The test was performed on different clean, uniform samples of crushed rock.
