Hierarchical creep cavity formation in an ultramylonite and implications for phase mixing [PDF]

open access: yes, 2017
Establishing models for the formation of well-mixed polyphase domains in ultramylonites is difficult because the effects of large strains and thermo-hydro-chemo-mechanical feedbacks can obscure the transient phenomena that may be responsible for domain ...

Sensitivity analysis of GSI based mechanical parameters of the rock mass [PDF]

open access: yes, 2014
The purpose of this paper is to analyze the sensitivity of the various constants of the different mechanical equations which depends on the Geological Strength Index (GSI) and the disturbance factor (D). Recently, both the Hoek-Brown failure criteria and

Population genetics of self-incompatibility in a clade of relict cliff-dwelling plant species [PDF]

open access: yes, 2016
The mating systems of species in small or fragmented populations impact upon their persistence. Small self-incompatible (SI) populations risk losing S allele diversity, responsible for the SI response, by drift thereby limiting mate availability and ...

THE USE OF GEOLOGICAL STRENGTH INDEX GSI. RECOMMENDATIONS, LIMITATIONS AND RANGES OF VALUES IN MOST COMMON ROCK TYPES

open access: yesBulletin of the Geological Society of Greece, 2004
After one decade of application of the Geological Strength Index, GSI, and its extensions, in the quantitative characterisation of the rock mass, the present paper attempts to answer the questions that have been raised by the users about the determination of the GSI for various qualities of rock masses and various conditions.

Alternative models for the calculation of the RMR and Q indexes for granite rock masses [PDF]

open access: yes, 2007
Empirical classification systems like the RMR and Q are often used in current practice of geotechnical structures design built in rock masses. They allow obtaining an overall description of the rock mass and the calculation, through analytical ...

Slope Stability Analysis Using Limit Equilibrium Method in Nonlinear Criterion

open access: yesThe Scientific World Journal, 2014
In slope stability analysis, the limit equilibrium method is usually used to calculate the safety factor of slope based on Mohr-Coulomb criterion. However, Mohr-Coulomb criterion is restricted to the description of rock mass. To overcome its shortcomings,

Stability Analysis for Ground Uplift in Underground Storage Caverns for High Pressurized Gas using Hoek-Brown Strength Criterion and Geological Strength Index (GSI)

open access: yesJournal of Korean Society For Rock Mechanics, 2014
Abstract A simple analytical approach for stability assessment of underground storage caverns against ground uplift of overburden rock above the rock caverns for high pressurized fluid such as compressed air energy storage (CAES) and compressed natural gas (CNG) was developed.
