The text begins with coverage of overall stability, earth pressure and strut force, retaining wall responses, and ground movements. Numerical modeling and computer codes are also outlined in detail. Final chapters conclude with an examination of the determination of excavation responses of urban adjacent utilities and failure analysis based on several case histories.
This book will be ideal for those that need the latest knowledge in both theory and practical application for deep excavation problems.
- Presents the latest theory and knowledge surrounding deep braced excavations
- Systematically outlines theory, field reports, calculations, and back analysis, making it much easier to master the work relevant with deep braced excavations
- Provides detailed visual elements and hyperlinks to additional images and video for case excavations to enhance understanding
Geotechnical design engineers and researchers in geotechnical engineering, geological engineering, or civil engineering. Engineers working in infrastructure sectors
