Informationen zum Autor Gregory B. Baecher is the author of Reliability and Statistics in Geotechnical Engineering, published by Wiley. John T. Christian is the author of Reliability and Statistics in Geotechnical Engineering, published by Wiley. Klappentext Risikoanalyse und Zuverlässigkeitsstudien sind in Theorie und Praxis der Geotechnik von wachsender Bedeutung. Jetzt endlich gibt es auch ein Buch, das sich ausführlich mit diesem Thema beschäftigt und das sich mit Sicherheit einen Platz in geotechnischen Studiengängen und in der Praxis erobern wird. Abgehandelt werden hier auch Themen, zu denen man ansonsten nur spärliche Informationen findet, wie die räumliche Variabilität und stochastische Eigenschaften geologischer Materialien. Zusammenfassung Risk and reliability analysis is an area of growing importance in geotechnical engineering, where many variables have to be considered. Statistics, reliability modelling and engineering judgement are employed together to develop risk and decision analyses for civil engineering systems. Inhaltsverzeichnis Preface.
