摘要:Rocks that are far removed from caverns or tunnels peripheries and subjected to high geostress may undergo ‘deep fracturing’. Deep fracturing of hard rock can cause serious hazards that cause delays and increase the cost of construction of underground caverns with high sidew...

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)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)A weak interlayer zone (WIZ) is a rock mass system with poor mechanical properties, large-scale random distribution, water softening, causing an adverse effect on the safety of the construction and project progress. To investigate the fracture process and the mechani...

摘要:Abstract(#br)The research was focused on the execution of true triaxial compression tests and adopted acoustic emission (AE) and scanning electron microscopy (SEM). By doing so, the authors investigated the strength, deformation, AE, macroscopic and microscopic failure characteri...

摘要:Abstract(#br)The common practice in understanding some puzzling geotechnical and geomechanical issues by large-scale three-dimensional physical model tests is recently much improved by the introduction of 3D-printing technology which can realize the reconstruction of complex geol...

摘要:Abstract(#br)In a tunnel, instabilities in the surrounding rock mostly occur within the sidewalls and crown. After acquiring the rock mass structure, a combination of laboratory experiments, numerical simulations, and in situ monitoring data can permit a more reasonable stability...

摘要:Abstract(#br)The rockburst and spalling problems encountered in the Jinping Underground Laboratory are to be investigated using 3-D physical model testing. New similarity relationships for the brittleness, brittle–ductile transition and ductility characteristics of deep hard...

摘要:Abstract(#br)The stability of high sidewalls of large-span underground powerhouses will be a major issue when the cavern axis forms a small angle to the steeply inclined rock strata. A synthetic test scheme composed of four experiments was performed on two rocks with clear b...
