Features: Variable-section piles have evolved from the thousands-year-old constant-section piles and are the crystallization of the labor and wisdom of pile foundation technicians. Due to their high compressive and uplift bearing capacities, variable-section piles are widely used in engineering and have become a new and cutting-edge topic in contemporary pile foundation technology. There are many types of variable-section piles. To systematically and comprehensively discuss the interaction mechanism between variable-section piles and soil, this book selects the new type of jacked expanded disc piles as a representative to introduce the main types of variable-section piles, the differences between variable-section piles and constant-section piles, construction techniques, bearing capacity calculations, design basis, and the interaction mechanism with soil. The content of the entire book is based on measured data, grounded in theoretical calculations, and employs numerical simulation techniques to study the interaction mechanism between variable-section piles and soil, thereby meeting the needs of engineering design and achieving the purpose of popularization and application. The book consists of 8 chapters, including an overview of variable-section piles, the formation mechanism of jacked expanded disc piles, the cavity expansion theory, the bearing capacity theory, settlement calculations, failure mechanisms, numerical simulation calculations, and optimization design. This book can be used as a reference for pile foundation engineering designers and construction personnel, as well as for researchers in civil engineering, university teachers, and graduate students.
