... relationship. Krajcinovic (1982) establishes a statistical damage constitutive model with the strain equivalence theory and statistical damage theory. The model includes the following three important parts. The first part is the damage constitutive relation. The strain equivalence damage model has a clear...

... methods measuring roughness. The 3D laser instrument to record the roughness topography is further explained. Finally, a 2-D profile of a rock joint is scanned and interpreted before and after a shear test. Introduction 1.1 Rock mass Properties of a rock mass are very well related to its joints...

... Abstract Following the previous work about the relation between permeability evolution and rock creep deformation [1–2], triaxial creep tests of volcanic breccias under various seepage pressures were performed on rock specimens and their lateral deformation behavior in the accelerated creep...

... technology (COSTT) uniaxial test of cement ore in Dong Guashan, the relations were analyzed between the caking property, caking time and loads. The results show: it is the certain positive relation between the sulfured cement strength and loads, during the same time. When loads set, the strength increased...

... mechanics theory. The damage parameters were identified from the stress-strain relation obtained from the mechanical test results. The effect of degradation was inferred by investigating the change in the damage parameters of the degraded rock. Moreover, finite element simulations based on an analytical...

... ABSTRACT Empirical rock failure criteria generally relates lateral stresses to axial strengths by a particular equation in which uniaxial tensile and/or compressive strengths are to be estimated from the failure criterion by applying the obtained parameters from triaxial datasets...

... empirical relation between the end bearing capacity and the unconfined compressive strength of intact rock, based on a database of 39 test shafts. O'Neill and Reese (1999) recommended using this method when the rock contains mostly closed, horizontal discontinuities. Based on load test data of rock socketed...
