ABSTRACT
Realization of structures always makes use of the soil on which, in which, or with which they are built. Whenever engineers find that the natural conditions of the soil are inadequate for the envisaged work, they are faced with the following well-known alternatives of bypassing the unsuitable soil in choosing a deep foundation, removing the bad soil and replacing it with the appropriate soil, redesigning the structure for these conditions, and improving these conditions to the necessary extent. Deep vibratory sand compaction is a simple concept, and, therefore, design and quality control of compaction in cohesionless soils have remained almost entirely empirical. Since the development of vibro compaction during the 1930s and vibro replacement stone columns in the 1970s, they have become the most frequently used methods of soil improvement worldwide because of their unrivalled versatility and wide range of application. This chapter presents an overview of this book.
