Estimating rock mass elastic modulus from seismic resonance measurements
Measuring the elastic modulus of in-situ rock masses over scales of tens of meters remains an important challenge in experimental rock mechanics. We present a new approach using ambient resonance measurements of freestanding rock masses to identify vibrational modes, which are then matched with numerical models implementing bulk, globally representative material properties. The result is an exp...
متن کاملrecracking of jointed rock masses in the sydney basin, new south wales, australia*
fracture mapping of late permian-early triassic flat-lying sedimentary rocks in the sydney basin,new south wales, australia, shows that joints developed originally in extension were faulted in subsequentevents. joints with a regional distribution fall into two (early and late) formed groups. group i joints propagatedhorizontally and never interfered with each other. these joints were subsequent...
متن کاملevaluation of rock mass deformability
One of the most important effective parameters in design of engineering structures is deformability of rock mass. Benchmark of rock mass deformability is the deformation modulus that directly or indirectly obtained. Since the determination of rock mass deformation modulus indirect method by in-situ tests is time-consuming, costly and difficult from executive operations aspect, so it’s correctly...
متن کاملUnusually Large Tumor in a Sydney Rock
An unusually large neoplasm with a volume approximately one-eighth that of the body volume of its host, a Sydney rock oyster (erassostrea commercialis), is described and discussed. As in previously described neoplasms of this type, the surface had deep crypts. Microscopic examination revealed a papillary structure throughout. The villi were composed of stratified or pseudostratified atypical ep...
متن کاملA model for estimation of stress-dependent deformation modulus of rock mass
Deformation modulus of rock mass has a significant role in the support design of an underground excavation. It is determined by expensive in-situ tests or by empirical models. Existing models for estimation of deformation modulus do not consider its stress dependence. Herein, data from several sources is used to develop a stress- (depth-) dependent relation for estimation of deformation modulus...
