... application to rock monitoring have been reported (Goodman and Blake, 1966; Hardy, 1981; Nakajima et al., 1988). Although great deal of works were carried out in respect to AE monitoring in rock, successful results to evaluate and predict slope failure are quite few. This is partially because AE sensors are...

... ABSTRACT: Post-mortem analyses of seven slope failures in rock slope are reported. The analysis is based on simple force equilibrium of a block of rock surrounded with several planes of discontinuity and separated from the neighbouring rock mass in a rock slope. Driven by the own weight of the...
