Risk and reliability analysis is an area of growing importance ingeotechnical engineering, where many variables have to beconsidered. Statistics, reliability modeling and engineeringjudgement are employed together to develop risk and decisionanalyses for civil engineering systems. The resulting engineeringmodels are used to make probabilistic predictions, which areapplied to geotechnical problems. Reliability & Statistics in Geotechnical Engineeringcomprehensively covers the subject of risk and reliability in bothpractical and research terms * Includes extensive use of case studies * Presents topics not covered elsewhere--spatial variability andstochastic properties of geological materials * No comparable texts available Practicing engineers will find this an essential resource as willgraduates in geotechnical engineering programmes.

Probabilistic reasoning, statistical methods, and measures of engineering judgment are combined to develop a quantified approach for analyzing and managing risks in civil engineering systems and the applied earth sciences. The resulting risk analysis approach described in this book reflects an emerging trend in geotechnical engineering, natural hazards mitigation, infrastructure protection, and other civil engineering fields to directly and quantitatively deal with uncertainty. Reliability and Statistics in Geotechnical Engineering offers a much needed state-of-the-art reference for risk analysis in geotechnical engineering and geology.
Integrating theory and practical applications, this book:
Emphasizing both theoretical underpinnings and practical applications, this comprehensive text constitutes an invaluable reference for practising geotechnical engineers, geologists, university students, and civil engineers in general practice.
