Dear DVGI Members and Friends,

DVGI invites you to our October 2022 dinner meeting.The meeting will feature the 3rd Robert M. Koerner Award Lecturer, Professor Jie Han, Ph.D., PE, F.ASCE. Dr. Jie Han's topic for the meeting will be Geosynthetic-reinforced column-supported embankments: Bridging theory and practice.A presentation abstract and speaker bio is below.

 

Social hour will start at 5:30PM followed by dinner at 6:30PM with the presentation to follow.

 

We anticipate that 1 PDH will be awarded for attending.

 

Please note our vendor is requiring more advance notice for headcount than the past, therefore the registration deadline is Tuesday October 11, 2022.

Presentation Abstract

Geosynthetic-reinforced column-supported embankments: Bridging theory and practice

 

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 proposes 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, and verify this design procedure with two case studies of geosynthetic-reinforced column-supported embankments.

 

About the Speaker

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 a board governor of the ASCE Geo-Institute, 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 3rdRobert 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, and the 2018 ASCE Kansas City Section Engineer of Year Award. Prof. Han was elected to the ASCE Fellow in 2014.
