This book contains a prolific compilation of research on geotechnical engineering presented at the First Geotech Asia International Conference (GAIC 2025). The papers reflect dynamic engagement of researchers, engineers, and professionals from all over Asia to offer insights into ongoing developments and applied problem-solving.This publication brings together contributions across 19 technical themes, including cold region geotechnics, deep excavations, earthquake engineering, foundation systems, and underground construction. It also delves into artificial intelligence and machine learning applications, environmental and transportation geotechnics, site characterisation, slope stability, embankments and dams, and ground improvement techniques.It is intended for academics, practising engineers, consultants, contractors, industry professionals, government authorities, and students involved in geotechnical research, education, and design and implementation.The Open Access version of this book, available at http://www.taylorfrancis.com, has been made available under a Creative Commons [Attribution-Non Commercial-No Derivatives (CC BY-NC-ND)] 4.0 license
