The pneumatic flow mixing method was developed to stabilize dredged soil and surplus soil for promoting their beneficial use in 1999. The pneumatic flow mixing method is a new type of the ex-situ cement stabilization techniques, in which dredged soil and surplus soil is mixed with a relatively small amount of chemical binder without any mixing paddles and blades in a pipeline. When a relatively large amount of compressed air is injected into the pipeline, soil can be separated into small blocks. When binder is injected into the pipeline, the soil block and binder are thoroughly mixed by means of turbulent flow generated in the soil block during transporting. As this method has many benefits − rapid and large scale execution can be conducted with low cost − it has been applied to many land reclamation projects, backfilling behind earth retaining wall projects and shallow stabilization projects using dredged soils and surplus soils. The Pneumatic Flow Mixing Method is a useful reference tool for engineers and researchers involved in admixture stabilization technology everywhere, regardless of local soil conditions and a variety in applications.

The Deep Mixing Method (DMM), a deep in-situ soil stabilization technique using cement and/or lime as a stabilizing agent, was developed in Japan and in the Nordic countries independently in the 1970s. Numerous research efforts have been made in these areas investigating properties of treated soil, behavior of DMM improved ground under static and d

This practical guide covers the investigation, design, and execution of ground improvement in coastal areas. It explains how to decide whether ground improvement is necessary, which method to choose, and how to design and execute it. Recognising the soft ground commonly found in coastal areas, the book introduces various ground improvement technologies including seismic reinforcement and liquefaction countermeasures and addresses the measures to be taken to sustain ground against external forces. Reliable Japanese ground improvement technologies are presented as well as the latest Building Information Modelling (BIM/Information and Communication Technology (ICT) used in their execution. The book also includes measures that can be taken against contaminated soil and considers ground improvement design on site. Unique focus on coastal applications Summarises leading edge Japanese practice The book suits professionals in the ground improvement industry, especially geotechnical designers and contractors.

This proceedings volume for the 4th international conference CIGOS 2017 (Congrès International de Géotechnique - Ouvrages - Structures) presents novel technologies, solutions and research advances, making it an excellent guide in civil engineering for researchers, students, and professional engineers alike. Since 2010, CIGOS has become a vital forum for international scientific exchange on civil engineering. It aims to promote beneficial economic partnerships and technology exchanges between enterprises, worldwide institutions and universities. Following the success of the last three CIGOS conferences (2010, 2013 and 2015), the 4th conference was held at Ho Chi Minh City University of Technology, Ho Chi Minh City (Saigon), Vietnam on 26 to 27 October 2017. The main scientific themes of CIGOS 2017 were focused on ‘New Challenges in Civil Engineering’.

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.
