Book Description

The deep mixing (DM) method developed in Japan and Sweden in the 1970s has gained popularity worldwide. The DM-improved ground is a composite system comprising stiff stabilized soil and unstabilized soft soil, which necessitates geotechnical engineers to fully understand the interaction of stabilized and unstabilized soils and the engineering characteristics of in-situ stabilized soil. The success of the DM project cannot be achieved by the well-determined geotechnical design alone but is guaranteed only when the quality and geometric layout envisaged in the design is realized in the field with an acceptable level of accuracy. The process design, production with careful quality control and quality assurance are the key issues in the DM project. This book is intended to provide the state of the art and practice of quality control and assurance on deep mixing in detail based on the experience and research efforts accumulated in the past 50 years.

Masaki Kitazume graduated from Tokyo Institute of Technology in 1979, and obtained his Master of Engineering in 1981. Then he joined the Port and Harbour Research Institute, Ministry of Transport and has been the head of the Soil Stabilization laboratory and has worked on the interaction of improved ground and soft ground. In 1994, he got a Doctor of Engineering from Tokyo Institute of Technology on the design of stability of Deep Mixing improved ground. In 2011, he was invited to become professor of the Department of Civil and Environmental Engineering, Tokyo Institute of Technology.
He has published many papers, mainly on the geotechnical aspects of soil stabilization, ground improvement and centrifuge model testing. He also published three books from Balkema Publishers and Taylor & Francis, on Deep Mixing Method, Sand Compaction Pile Method and Pneumatic Flow Mixing Method.
He was awarded the Geotechnical Engineering Development award from the Japanese Society of Soil Mechanics and Foundation Engineering in 1992, the Minister of Transport Award in 2000, and Continuing International Contribution Awards, Japan Society of Civil Engineers in 2006, Geotechnical Engineering Research Achievements Award, the Japanese Society of Soil Mechanics and Foundation Engineering in 2018, and Telford Premium Prize, ICE Awards in 2019.
