n this special issue of Geosynthetics magazine, Jie Han, Ph.D., P.E.,
F.ASCE, of the University of Kansas, the 2021 Dr. Robert M. Koerner
Lecturer and Awardee, has written a fascinating article, " GeosyntheticReinforced
Column-Supported Embankments: Improving Practice with
Better Theory, " summarizing the key contents of his Koerner lecture and
emphasizing the important point: Improving practice with better theory.
This is the first time Geosynthetics magazine has published the principal
content of a Koerner lecture.
This issue also includes an article by Brian Fraser and Mike Neal, an

interesting case study on geosynthetic cofferdams entitled " Geosynthetic
Portable Cofferdams for Civil Construction Applications. " As the authors
note, " Portable geosynthetic cofferdams are typically lighter-weight modular
systems produced from geomembrane and geotextile fabrics. They limit the
impact of construction-generated silt and sedimentation when excavating
in submerged or dredging areas, which lessens the environmental impact.
Most systems are also modular in design, allowing for bends and turns in
the project waterway. "
And our third feature takes us to the Russian Federation for " Construction
of Roads in Underground Mines with 3D Geocells, " a case study by A.
Goncharov, A. Kolesnikov and A. Korotkevich. The authors did testing
using yellow-colored geocells (for underground visibility) with a specially
designed fastening key that can quickly connect the geocell sections. As the
authors note, " The specialists of Russia-based geosynthetics manufacturer
PRESTORUS LLC found a solution to this problem and developed a new
generation of 3D geocells. The patented production technology includes
the use of ultra-strong reinforcing threads in the polyethylene tape, which
prevents plastic deformation of the cells. Thanks to the reinforcement of
the tape, these geocells are stronger and more reliable than standard 3D
geocells. Thus, the reinforced geocell does not stretch under constant loads
and elevated temperatures, and it maintains its geometric dimensions and
shape-particularly useful in underground mining roads, which are often
subject to rapid destruction of the structure due to mechanical loads from
heavy equipment. "
And this issue also announces GeoNashville, to be held in Tennessee, Nov.
4-5, 2021. The all-plenary event will be the first in-person U.S. geosynthetics
conference since the pandemic began. Read about it in both the Geosynthetics
Conference Watch and the GMA News columns.
