The fracture of interfacial crack is the main failure type jointed rock mass. Therefore, it very important to study For similarity mass and composites (all are composed by two parts, intact materials their contact interfaces), interface mechanics widely used for analysis (bimaterials) can be applied based on basic theories mechanics, was analyzed, one new criterion initiation proposed. Moreover...

Rock art offers traces of our most remote past and was made with mineral organic substances in shelters, walls, or the ceilings caves. As it is notably fragile, fortunate that some instances remain intact—but a variety natural anthropogenic factors can lead to its disappearance. Therefore, as valuable cultural heritage, rock requires special conservation protection measures. Geomatic remote-sen...

The geometrical and mechanical properties of non-persistent joints as well the behavior intact rock (rock bridges) are significantly effective in shear strength weakness planes containing joints. Therefore, comprehensive knowledge mechanism both bridges is required to assess planes. In this study, specimens a single rough joint investigated. A novel procedure was used prepare cast embedding (di...

Tunnelling in bedded shale rocks induces damage around the excavation. Consequently, rock mass excavation damaged zone (EDZ) shows different thermo-hydro-mechanical (THM) properties from intact rock. In turn, material close to tunnel wall is affected by seasonal fluctuations temperature and relative humidity (RH) variations associated with ventilation, impacting total suction saturation state o...

A numerical characterization of a fractured rock mass and its mechanical behavior using discontinuum approach was carried out utilizing lattice-spring-based synthetic (LS-SRM) models. First, LS-SRM models on laboratory scale were created to reproduce standard tests Triassic sandstone samples from quarry in Germany. Subsequently, the intact properties upscaled an element volume representative fo...

The Yucca Mountain Project is conducting a Single Heater Test (SHT) in the Exploratory Studies Facility at Yucca Mountain. This report describes the thermal and thermomechanical data collected for the SHT through the third quarter of heating (through 31 May 1997) and compares the data with numerical predictions in order to gain insight into the coupled Thermal-Mechanical-Hydrologic-Chemical pro...
