... for the purposes of this paper is 90 for the estimation of the structural properties of the rockmass. The total 90 samples taken have a constant height/width and height/length ratio of 2 and are of varying height (1, 2, 3, 5, 7, 10, 12, 15 and 20 m). For each separate sample size, ten samples were extracted from...

... perpendicular sample size fracture surface rock mechanics isrm13 Abstract Tensile strength of rock samples is measured by direct and indirect tensile tests in accordance with standard guidelines. Due to the difficulties in performing direct tensile test, the indirect tensile (Brazilian) test...

... role in this approach plays a proper determina- tion of the RVE size, NRVE, as well as the size, n, of the sample. The both values are related to each other, i.e. larger size of RVE 2107 then a smaller sample size n can be used or inversely smaller size of RVE requires necessity of larger size...

... that the structural non-stationarity of roughness controls the damage zones and asperities degradation of the fracture surfaces and the contact areas of the fracture largely depend to the sample size. It is concluded that for accurate characterization of the morphological and mechanical properties of rock joints...

... properties of the concrete fracture replicas. Four concrete replicas having same geometry from each sampling size were sheared under four different normal loads. The results show that normal and shear stiffness and peak shear strength decrease with increasing sample size and decreasing normal stress...

.... According to these, small sample sizes lead to higher peak shear strength values than can be activated in-situ and are therefore unsafe to use in stability calculations. The consequences of the results of the basic investigations for slope stabilization by means of anchors are shown in a case study...
