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. 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.

This book summarizes the application of soft computing techniques, machine learning approaches, deep learning algorithms and optimization techniques in geoengineering including tunnelling, excavation, pipelines, etc. and geoscience including the geohazards, rock and soil properties, etc. The book features state-of-the-art studies on use of SC,ML,DL and optimizations in Geoengineering and Geoscience. Considering these points and understanding, this book will be compiled with highly focussed chapters that will discuss the application of SC,ML,DL and optimizations in Geoengineering and Geoscience. Target audience: (1) Students of UG, PG, and Research Scholars: Several applications of SC,ML,DL and optimizations in Geoengineering and Geoscience can help students to enhance their knowledge in this domain. (2) Industry Personnel and Practitioner: Practitioners from different fields can be able to implement standard and advanced SC,ML,DL and optimizations for solvingcritical problems of civil engineering.

Special Rock Mechanics for Cultural Heritage and Reservoir Slopes: Theory, Modeling, and Applications presents a comprehensive study of the unique challenges in understanding and preserving rock formations in culturally significant sites and reservoir slopes. The book begins by outlining the theoretical foundations and practical applications of special rock mechanics, emphasizing the importance of addressing creep and salt weathering processes in sandstone. Advanced modeling techniques, including creep simulation and contact constitutive models, are discussed to elucidate sandstone deterioration mechanisms, while numerical simulations shed light on salt weathering effects and the role of nano-lime reinforcement in mitigating damage. Comparative discussions highlight common failure modes and provide methodological recommendations for modeling workflows. Applications extend to aging deterioration models, hygrothermal-salt interactions, anchoring simulations, and landslide-generated impulse wave modeling, demonstrating the versatility of special rock mechanics in real-world scenarios. Innovative rock damage detection methods are explored, including micro-CT imaging, NMR, SEM, XRD, acoustic emission testing, and 3D laser scanning, integrated into a framework for precise damage identification and parameter assessment. The book concludes with a forward-looking perspective on future research directions. This volume is an essential resource for engineers, geoscientists, and conservationists seeking to apply advanced rock mechanics principles to safeguard cultural heritage and ensure the stability of critical reservoir slopes.

To prevent the collapse of dangerous rock masses on steep rocky reservoir banks which can cause casualties and property loss, it is essential to design and conduct practical experiments to quantify the evolution processes of the reservoir banks and control such dangerous rock masses.Using the Jianchuandong Dangerous Rock Mass project as a case study, this book generalizes the mechanical model of the project to show how improved equipment can be used to measure the mechanical state transition under the continuous action of axial pressure. It details a series of experiments to study the evolution of a severely steep rocky reservoir bank, which comprehensively consider the influence of hydraulic coupling, dry-wet cycles, axial pressure, and time-dependent effects. The results support a new method for determining the stability of dangerous rock masses on reservoir banks.Combines engineering principles, real data, experimental methods and resultsProvides a complete research method for investigating hydrogeology failure processesThe book suits practitioners in hydropower engineering, engineering geology, and disaster protection.

This book presents basic design theories and principles and provides detailed analysis for excavation failure cases based on the author's research experience, aiming to provide a comprehensive picture of the subject matter. It focuses on the basal heave stability analysis, the apparent earth pressure as well as the strut force determination, the retaining wall deflection, the ground settlement, the protection measures such as jet grouting slabs or piles, case reports, back analysis methodology. From the very basic to the most advanced, it tries to attain theoretical rigorousness and consistency. On the other hand, this book also tries to cope with design practice, implemented by the recent publications from the authors. Students, researchers, and design engineers working in the field of civil engineering could benefit from this book.

This book presents the application of a comparatively simple nonparametric regression algorithm, known as the multivariate adaptive regression splines (MARS) surrogate model, which can be used to approximate the relationship between the inputs and outputs, and express that relationship mathematically. The book first describes the MARS algorithm, then highlights a number of geotechnical applications with multivariate big data sets to explore the approach’s generalization capabilities and accuracy. As such, it offers a valuable resource for all geotechnical researchers, engineers, and general readers interested in big data analysis.
