The volume contains research studies that cover a wide range of topics related to ground improvement and subsurface structures. This selection of papers represents the state-of-the-art in the analysis and design of different techniques of the ground improvement and deep mixing techniques. It provides engineers and researchers with an update on the recent development in ground improvement techniques and on the analysis and design of important soil structures problems. The volume is based on the best contributions to the 2nd GeoMEast International Congress and Exhibition on Sustainable Civil Infrastructures, Egypt 2018 – The official international congress of the Soil-Structure Interaction Group in Egypt (SSIGE).
