Texte du rabat

Rockfall Engineering is an up-to-date, international picture of the state of the art in rockfall engineering.
The three basic stages of rockfalls are considered: the triggering stage, the motion stage, and the interaction with a structure stage; along with contributions including structural characterization of cliffs, remote monitoring, stability analysis, boulder propagation, design of protection structures an risk assessment.
Academic contributions are illustrated by practical examples, and completed by engineering contributions where practical purposes are thoroughly considered. This title is intended for engineers, students as well as researchers.

Résumé
This book offers an up-to-date, global picture of the state of the art in rockfall engineering. It describes the three basic stages of rockfalls, including the triggering stage, the motion stage, and the interaction with a structure stage.
