This book aims to introduce the principle and design of various foundations, covering shallow foundations, mat foundations, earth retaining structures, excavations, pile foundations, and slope stability. Since the analysis and design of a foundation are based on the soil properties under short-term (undrained) or long-term (drained) conditions, the assessment of soil properties from the geotechnical site investigation and the concept of drained or undrained soil properties are discussed in the first two chapters. Foundation elements transfer various load combinations from the superstructure to the underlying soils or rocks. The load transfer mechanisms, vertical stress or earth pressure distributions, and failure modes of each foundation type are clearly explained in this book. After understanding the soil responses subjected to the loadings from the foundation, the design methods, required factors of safety, and improvement measures for each foundation type are elaborated. This book presents both theoretical explication and practical applications for readers to easily comprehend the theoretical background, design methods, and practical applications and considerations. Each chapter provides relevant exercise examples and a problem set for self-practice. The analysis methods introduced in the book can be applied in actual analysis and design as they contain the most up-to-date knowledge of foundation design. This book is suitable for teachers and students to use in foundation engineering courses and engineers who are engaged in foundation design to create a technically sound, construction-feasible, and economical design of the foundation system.

Excavation is an important segment of foundation engineering (e.g., in the construction of the foundations or basements of high-rise buildings, underground oil tanks, or subways). However, the excavation knowledge introduced in most books on foundation engineering is too simple to handle actual excavation analysis and design. Moreover, with economic development and urbanization, excavations go deeper and are larger in scale. These conditions require elaborate analysis, design methods and construction technologies.This book is aimed at both theoretical explication and practical application. From basic to advanced, this book attempts to achieve theoretical rigor and consistency. Each chapter is followed by a problem set so that the book can be readily taught at senior undergraduate and graduate levels. The solution to the problems at the end of the chapters can be found on the website (http://www.ct.ntust.edu.tw/ou/). On the other hand, the analysis methods introduced in the book can be used in actual analysis and design as they contain the most up-to-date knowledge. Therefore, this book is suitable for teachers who teach foundation engineering and/or deep excavation courses and engineers who are engaged in excavation analysis and design.

This edited book's theme is organized as a part of the GeoMEast 2019 International Congress and Exhibition that was held in Cairo, Egypt, on November 10–14 2019.The editors like to express their deep appreciation and gratitude to the authors for their valuable contributions to the GeoMEast 2019 proceedings and to all session chairs and reviewers for their sincere efforts to make this book a reality. The editors are very grateful to have this opportunity to participate in organizing this GeoMEast 2019 conference and hope that this book theme is a valuable reference to the civil/geotechnical engineering community worldwide.

With continued economic development and increasing urbanization, excavations go deeper and become larger in scale, and are sometimes even carried out in difficult soils. These conditions require advanced analysis and design methods and construction technologies. Most books on general foundation engineering introduce the basic analysis and design of excavation, but do not delve into practical considerations. This book examines both theory and practice, from basic to advanced, and discusses the major methods currently in practice around the world. Each chapter also includes problems and their solutions to develop a practical, real-world understanding.
