Abstract Evaluation of rock mass deformability is an important but very challenging task in
the analysis and design of underground structures in rock. Although various empirical …

More often than not, it is difficult or even impossible to obtain directly the specific rock
parameters of interest using in situ methods. The procedures for measuring most rock …

The accuracy of elastic analytical solutions and numerical models, widely used in
volcanology to interpret surface ground deformation, depends heavily on the Young's …

The equivalent elastic modulus is a parameter for controlling the deformation behavior of
fractured rock masses in the equivalent continuum approach. The confining stress, whose …

A constitutive model for describing the nonlinear mechanical behavior of different types of
intact rock subjected to complex 3D stress states is presented. It is formulated on the basis of …

A new closed-form solution is presented for the stress and displacement distribution
surrounding circular openings with finite external radii that are subject to uniform internal …

The lack of understanding of plastic hardening (softening) laws, especially under anisotropic
stress conditions, results in inappropriate geotechnical management. Most of the yielding …

We carried out laboratory experiments under dry conditions on limestone core specimens of
Sarvak formation obtained from an oil well in the southwest of Iran. Our objective was to …

The accurate prediction of strength and deformability characteristics of rock mass is a
challenging issue. In practice, properties of a rock mass are often estimated from available …

A reasonable prediction of the elastic modulus of rock and rock mass can provide sound
basis for the design in tunnels and underground caverns. It is observed from the laboratory …
