The Pneumatic Flow Mixing Method


Book Description

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


Book Description

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




Soft Ground Engineering in Coastal Areas


Book Description

This volume contains the papers contributed to the Nakase Memorial Symposium with the theme: Soft Ground Engineering in Coastal Areas, held in Yokusuka, Japan in November 2002. The meeting was organized as a tribute to Professor Ako Nakase, and was attended by 125 participants including his Japanese colleagues and friends from overseas. The topics covered included: fundamental Characteristics of Clay Soils; Estimation of consolidation settlement in large-scale reclamation; Soil improvement methods in coastal areas; Reuse of dredged soils and behaviour of coastal structures under earthquake; and Evaluation for the stability of coastal structures.




Ground Improvement for Coastal Engineering


Book Description

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.




Proceedings of the 4th Congrès International de Géotechnique - Ouvrages -Structures


Book Description

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’.




Coastal Geotechnical Engineering in Practice, Volume 2


Book Description

The International Symposium on "Coastal Geotechnical Engineering in Practice (IS-Yokohama 2000)" was held from 20 to 22 September 2000 in Yokohama, Japan and sponsored both by TC-30 of ISSMGE on "Coastal Geotechnical Engineering" and by the Japanese Geotechnical Society (JGS). This symposium attracted 310 participants from many countries and IS-Yokohama 2000 is remembered as a successful event for gathering valuable information and experiences from various researchers and case studies on soft ground engineering technology in coastal areas. During the symposium participants heard invited leading experts present lectures and reports and had a chance to meet with representatives of various research fields of interest. As a fulfilment of the promis made during the symposium, a second volume was produced after the conference with contributed paper of those presentations in keynote addresses, special lectures, project reports and special discussion sessions, with the hope that this will be a valuable reference for engineers, academics, consultants and those who are interested in Coastal Geotechnical Engineering.
