This book include research studies which deal with the attempts to address new solutions for challenges in geotechnical engineering such as characterization of new materials, application of glass fibre, geotextile fabric and permeable concrete, new numerical methods for traditional problems and some other geotechnical issues that are becoming quite relevant in today's world. The book adds to the geotechnical engineering field which still bears lots of big challenges. It contributes to make the civil infrastructures more sustainable using new technologies and materials that have been proposed and applied in various fields. Papers were selected from the 5th GeoChina International Conference 2018 - Civil Infrastructures Confronting Severe Weathers and Climate Changes: From Failure to Sustainability, held on July 23 to 25, 2018 in HangZhou, China.
