Soil Mechanics

Informationen zum Autor Roberto Nova obtained his PhD from the University of Cambridge and then became Professor of Soil Mechanics at Dipartemento Ingegneria Strutturale del Politecnico in Milan. Klappentext Knowledge of the behavior of soil mechanics is essential for forecasting the internal displacements and actions of any construction. This book, although theoretical at first glance, also offers a more practical scope, giving readers adequate tools to plan geotechnical projects correctly.
