Paper presented at the Gulf Rocks 2004, the 6th North America Rock Mechanics Symposium (NARMS), June 5–9, 2004
Paper Number: ARMA-04-517
... ABSTRACT: The point estimation method can be applied to the safety factor (SF) equation for any specified rock slope failure mode (such as plane shear, step path, or wedge) to obtain reliable estimates of the mean and standard deviation of the SF probability distribution. A gamma probability...

Paper presented at the Gulf Rocks 2004, the 6th North America Rock Mechanics Symposium (NARMS), June 5–9, 2004
Paper Number: ARMA-04-584
... ABSTRACT: This paper presents a preparation technique of interstratified rock block the overall mechanical properties of which are similar to the transversely isotropic rocks. Strength criterion and failure modes of the interstratified rock are studied with both theoretical and experimental...

Paper presented at the 4th North American Rock Mechanics Symposium, July 31–August 3, 2000
Paper Number: ARMA-2000-0539
... ABSTRACT ABSTRACT: A computer analysis of bench stability has been developed to account for multiple occurrences of potential slope-failure modes in discontinuous rock masses. Bench-scale plane shears and tetrahedral wedges are simulated and stochastically analyzed to estimate the probability...

Paper presented at the 4th North American Rock Mechanics Symposium, July 31–August 3, 2000
Paper Number: ARMA-2000-1195
... ABSTRACT : To simulate soft rocks, (a) a mixture of plaster of Paris, sand and water was used as a model material. Thin galvanized sheets were used to create joints in blocks made out of the model material. To investigate the failure modes and strength, jointed model material blocks of size 30...

... with the generalized delta rule by Rumelhart et al.(1986) Some neural networks have been introduced in rock engineering field. Among them are networks to predict elastic compressibility of sandstone specimens (Zahng et al, 1991) and to infer failure mode of rock mass (Lee and Sterling, 1992). Conventional artificial...
