Description

The fourth in the highly respected Short Course Series, A Short Course in Soil-structure Engineering of Deep Foundations, Excavations and Tunnels, focuses on the three major geotechnical challenges of static soil-structure interaction problems. Deep foundations – piles, barrettes, Multi-propped deep excavations and Bored and open face tunnels beneath cities.

This book gives both students and practising civil engineers an authoritative review of the state-of-the-art of designing deep foundations, excavations and tunnels. In addition, the case studies and numerical modelling presented will give valuable insights into the challenges of soil-structure engineering.
