Design of Deep Braced Excavation in Urban Geotechnical Environments presents the design and calculation of deep braced excavation in urban geotechnical environments considering the soil characteristics of spatial variability and anisotropy, as well as excavation responses of urban adjacent utilities such as pipelines, tunnels, foundation piles and buildings. With economic development and further urbanization, excavation goes deeper, longer, and larger in scale. These conditions require advanced analysis and design methods. 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 outlined in detail. The authors then take a close look at the design of jet grouting for deformation control, instrumentation and back analysis for excavation, and the characteristics of deep braced excavation in complex geological environment. The 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 provides the latest knowledge in both theory and practical application for geotechnical design engineers working on 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
