State of the art in deep mixing technology: part I. Basic concepts and overview

Abstract

Today’s competitive construction industry is highly dependent on effective use of existing and innovative technologies. In many situations the key issue is not how to break through technological barriers but how to put existing concepts to the best possible use. Whereas the basic knowledge behind many developed techniques can be found in engineering textbooks, the complex issues related to know-how of analysis and design, construction techniques, and quality monitoring, developed based on regional experiences, have not been widely available to engineers working in different countries. In a series of papers, the aim is to examine issues, concepts, and the latest advancements in research and development of deep soil mixing technology. The focus is on presenting basic concepts, various application areas, considerations for analysis and design, construction techniques, methods of quality control, and so on. A large number of case histories of deep mixing projects, applied in different countries, are collected to portray various functions of deep mixing; along with references to exemplify the current practice and the present understanding of the technology. This first paper emphasizes basic concepts, definitions, classifications, and historical developments related to deep mixing technology around the world.
