... of distinct fracture sets in a rock mass and associated influence on the equivalent permeability of the rock mass, this study adopts statistical analyses to estimate the hydrogeological characteristics from a series of in-situ test results. There are 10 boreholes drilled within a radius of 9.2m in a wells...

... a small diamond impregnated blade and monitoring of the strains which are relieved normal to the slot direction. The aim of this paper is to evaluate the effects of key test parameters on the slotter test results. A precise 3D numerical model of typical slotter test condition was constructed using...

... 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...

... propagation across such geological discontinuities. With the parameters fitted from a number of SHPB tests, the closure-pressure relation based on the three-phase medium model were compared with other test results and very good agreement was observed. Then, the three-phase filled joint model is adopted...
