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.
