.... Although it is important to explore the mechanical and hydraulic coupling of rock fracture/fracture network during hydraulic shearing, the laboratory experiments for exploring such coupling are very limited (Ye and Ghassemi, 2018; Ishibashi et al., 2018). This study presents the experimental results those...

Using the same Young s modulus, Poisson s ratio, density and strengths estimated from the experiments, our results suggest that the outcome of the ICZM and experiment showed large discrepancy especially for the intact stress wave propagation...

... of 551 m and six research modules. The maximum depth of the tunnel is about 120 m from the surface. The host rock is granite, which is considered as a potential host rock type for HLW disposal repository in Korea. Various in-situ tests and experiments have been carried out since 2007, and tracer test...

... analyses. The rock mass strength of the nuclear waste disposal site in Olkiluoto, Western Finland, was researched as a part of Posiva s Spalling Experiment (POSE). The POSE experiment was conducted as an in situ rock mass strength test that revealed the rock mass failure in Olkiluoto being governed...

In addition, a numerical simulation using ABAQUS is carried out to verify the validity of the suitable constitutive model, i.e. Cam-Clay model, and the rationality of the values of the parameters. Thus this research contributes a lot to the further study about...
