The unique structural characteristics and special symmetry of columnar jointed rock mass result in its complex mechanical properties strong anisotropy, which seriously affects the safety engineering construction. To better simulate natural mass, a geometric model reconstruction method based on single-random movement Voronoi diagram uniform seed points using feasible geological parameters horizontal polygon density, irregular factor, dip angle, strike transverse joint spacing, penetration...
Columnar jointed rock mass (CJRM) formed by intact divided special symmetrical columnar joints is a type of with poor mechanical properties, strong anisotropy, and weak self-supporting ability, severely affecting the excavation safety stability underground tunnels. In this study, taking Baihetan hydropower station as engineering background, CJRM geological numerical models different dip angles that combined well natural were generated based on statistical parameters site verified to have...
The generation of rock mass disasters in underground engineering essentially arises from the disruption original three-dimensional stress equilibrium caused by excavation and other activities, leading to redistribution fields. During process, undergoes complex dynamic processes involving loading unloading. This process promotes nucleation, initiation, propagation pre-existing cracks surrounding rock, resulting changes internal structure a weakening its strength. Eventually, this localized...
ABSTRACT This study investigates the fracture behavior of brittle solids with combined defects by prefabricating internal cracks in glass materials using three‐dimensional laser‐engraved crack (3D‐ILC) technology. The results physical and numerical experiments indicate that under biaxial compression, first appear on surface cavity, followed propagation prefabricated cracks. During propagation, these two attract each other, ultimately leading to coalescence. As geometric distribution changes,...
In order to ensure the successful construction and stable operation of deep engineering projects, significant progress has been made in researching underground rockburst issues from various perspectives. However, there have few systematic analyses overall research status date. this study, a bibliometric approach using CiteSpace software (version 6.2.R3) was employed visualize analyze knowledge maps 353 articles on collected Web Science core database 1996 2022. The results show that number...
Fiber-hybridization is an effective strategy to overcome the catastrophic fracture of fiber-reinforced polymer composites via achieving pseudo-ductility. However, demonstration pseudo-ductile behavior limited by low carbon fiber volume fraction, i.e. stiffness and strength, for traditional carbon/glass hybrid with all layers centralized in middle. In this work, a new layup concept based on layer dispersion was introduced improve fraction while maintaining behavior. Different configurations...
Dense nonaqueous phase liquid (DNAPL) is one of the main pollution sources underground environment. After DNAPL enters environment, migration and diffusion process has experienced a variety media, resulting in large-scale long-term pollution. To better understand residual dissolution fractures, visual experiment fracture was carried out using transparent model made glass material, changes morphology distribution crack were obtained. The results showed that front finger shaped displacement...
