The generalized Hoek-Brown (GHB) failure criterion can estimate the rock mass parameters required for mechanics–related analyses such as numerical modeling in geomechanics. determination of GHB has been developed field mechanics. Due to wide use Mohr-Coulomb and lack an existing relationship determining its a mass, equivalent (EMC) be derived from GHB. To determine differences these two criteri...

Lineer olmayan yenilme ölçütleri, kaya malzemelerinin çekme, basma, yanal basınç altında basma ve kırılgan-sünek geçişi gibi tüm aşamalarını temsil etme noktasında kullanışlı araçlardır. Hoek-Brown (H-B) ölçütü sağlam malzemesi için önerilmiş olan en önemli ölçütlerden birisidir mi sabiti ölçütün bir parçasıdır. ölçütünde farklı malzemeleri çizelgede önerilen değerlerden, üç eksenli deneylerind...

The Hoek-Brown (H-B) criterion is one of the most commonly used rock failure criteria in recent years. This includes a constant parameter called mi which fundamental for estimating strength. Due to importance H-B criterion, it necessary conduct comprehensive studies on various aspects effect this behavior rocks. Therefore, study, using numerical simulation Triaxial Compressive Strength (TCS) te...

Rock failure criteria are key input parameters for models designed to better understand the stability of volcanic rock masses. Cohesion and friction angle two defining material variables Mohr-Coulomb criterion. Although these can be determined from laboratory deformation experiments, they rarely reported. Tabulated data rocks, calculated using published triaxial results, show that cohesion decr...
