Geosynthetics have been successfully used to improve performance of column-supported embankments on soft soils. Geosynthetic-reinforced column-supported embankments involve complex load transfer mechanisms, including soil arching, tensioned membrane, and column-soil interaction. Different theoretical models are available to describe soil arching but often result in different predicted stresses because pattern and degree of soil arching depend on the magnitude of differential settlement between columns. Due to non-uniform deflections of geosynthetic reinforcement, tensile strains in the reinforcement are spatially distributed. This lecture will discuss a simplified and unified design procedure based on the ground reaction curve and considering subsoil resistance and tensioned membrane effects of strain strips to reasonably predict stresses, settlements, and tensile strains of the geosynthetic reinforcement, as verified with two case studies of geosynthetic-reinforced column-supported embankments.


Dr. Jie Han is a Roy A. Roberts (University) Distinguished Professor in the Civil, Environmental, and Architectural Engineering Department at the University of Kansas. He is the president of the ASCE Geo-Institute, the treasurer of the International Geosynthetics Society, the chair of the US Transportation Research Board (TRB) Transportation Earthworks committee, and the specialty chief editor of Frontiers of Built Environment. Prof. Han has gained extensive teaching, research, and industry experiences in geosynthetics, ground improvement, pile foundations, buried structures, and roadways. He is the sole author of the book entitled “Principles and Practice of Ground Improvement” and has published more 450 peer-reviewed journal and conference papers.  Prof. Han has been invited to give more than 200 keynote/invited lectures and short courses around the world, including the State of the Practice Lecture at the 21st Annual George F. Sowers Symposium in Atlanta, Georgia in 2018, the 18th UK IGS Lecture in London in 2018, and the 3rd Robert M. Koerner Award Lecture in 2021.  He has received numerous awards from the profession including but not limited to the 2014 the International Geosynthetics Society Award, the 2017 ASCE Martin S. Kapp Foundation Engineering Award, the 2018 ASCE Kansas City Section Engineer of Year Award, and the 2024 recipient of Irvin E. Youngberg Award in the Applied Sciences (the Kansas state higher education system’s most prestigious recognition for scholarly excellence).  Prof. Han was elected to the ASCE Fellow in 2014.
