This book examines the design and construction of stone columns, which is one of the ground improvement methods used for rehabilitating soft clay soils, layers, and also suitable for loose sand layers. The book consists of seven chapters. In the first chapter, an overview of various ground improvement methods, the history, and applications of stone columns are presented, followed by a detailed explanation of different construction methods for these columns. General explanations about the vibration process, equipment used in the construction of stone columns, and their performance relative to the type of soil are among other important topics discussed in the first chapter.
The second chapter focuses on settlement mechanisms, the arrangement of stone columns, the concept of a unit cell, and estimation of load-bearing capacity and settlement of individual and grouped stone columns. Stability analysis of embankments constructed on stone columns is also addressed in the final part of this chapter.
Chapter three deals with construction supervision, auxiliary instructions, and acceptance tests. The fourth chapter consolidates the results of studies conducted in the field of designing stone columns. Examples and case studies are presented in chapters five and six, respectively. Finally, chapter seven provides a summary and conclusion
