Reliability in Rock Engineering

by H. H. Einstein, Massachusetts Inst of Technology, Cambridge, United States,



Document Type: Proceeding Paper

Part of: Geotechnical Engineering Congress—1991

Abstract: This paper reviews approaches to reliability in rock engineering through a survey of methods developed at MIT. Since these methods are intended to be applied in engineering decisions, the paper is structured along the lines of a typical decision cycle. Specifically, this is done by first describing how uncertainties in rock properties are characterized, followed by relationships between these characteristics and performance. This provides the basis for various decision making procedures including procedures to collect more information. The decision cycle is illustrated with typical rock engineering problems in slope stability and tunneling.
