... 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...

... 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...

... will be less than the designed period if there is no groundwater supply system. It was also found that there is an approximately linear relation between groundwater inflow flux and permeability in the double logarithm space. On the stability of the caverns, it is shown that the stability of pillars between...

... 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...
