摘要:Abstract(#br)In order to effectively identify the loosened zone around underground openings by using continuum modeling, this paper proposes an index called elastic modulus deterioration index based on the following two steps. First, the response of surrounding rock mass in ...

摘要:Abstract(#br)In this study, a layered rock mass was regarded as a composite material, composed of interlayered intact rocks and bedding planes. Based on this assumption, we developed a transversely isotropic elastic–plastic model to describe the elastic response and post-pea...

摘要:Abstract(#br)Layered rock masses exhibit significant anisotropy in both the deformability and strength. Properties of this rock mass are largely affected by its bedding structure and also by the stress state change. For the purpose of characterizing these salient features using t...

摘要:Abstract(#br)The stability of large underground caverns in steeply dipping layered rock masses is not only affected by the engineering geological characteristics of surrounding rock masses, but also by the excavation sequences and reinforcement measures. Certain places around the...

摘要:Abstract(#br)An interlayer shear weakness zone (ISWZ) is a weak zonal geotechnical system of variable thickness that occurs between different rock strata (e.g., tuff and basalt). At the site of the future Baihetan hydropower station, Sichuan Province, China, because of the r...

摘要:Abstract(#br)Numerous collapses have occurred during the excavation of diversion tunnels in the thin and extremely thin layered rock strata at Wudongde Hydropower Station in China. Hence, a reliable method is required to predict the risk and the depth of collapse. However, b...

摘要:Abstract(#br)Interlayer shear weakness zone (ISWZ) is a widespread zonal weak geotechnical system with variable thickness in rock masses, representing a potential threat to the overall stability of structure constructed on or within the rock mass due to their relatively poor mech...

摘要:Abstract(#br)The representation of the surface of a rock fracture and a numerical method to simulate fluid flow in single fractures are the keys to understanding the hydraulic behaviour of rock fractures. In this paper, a cellular automaton (CA) approach is used to generate ...

摘要:The mechanical behaviours of layered rock mass exhibit significant differences in the directions parallel and vertical to the bedding planes. The deformation and failure of a layered rock mass has remarkable weak-plane dependence, which brings a major challenge to the contro...
