Tryst with geosynthetics - Vol.52(5), Oct - USA Springer 2022 - 1003-1053p.
Geosynthetics are progressively playing a dominant role in geotechnical engineering and geotechnology. The engineering aspects of geosynthetics are a discipline unto themselves, based on the principles of applied mechanics. Through this paper, the author highlights his experiences with geosynthetics. To date, much literature is available on various aspects and applications of geogrids and other geosynthetics. Not much can be reviewed on geocells. The author has intensely worked on several applications with geogrids, geocells, and drainage systems, with nonwoven and woven geotextiles as indispensable requirements of detailing. While only innovative applications with geogrids and drainage geocomposites have been illustrated, the author has majorly focussed on geocells. Geocells were at one point of time, the least understood geosynthetic materials. Geocells are one example where technology preceded the understanding of its engineering mechanics. This paper inter alia attempts to project theories defining the mechanics of geocells and analyses by simple methods that do not require sophisticated and expensive software. To highlight the practicality of the geocell systems, the paper includes several case studies. The objectives of the paper include projecting diverse applications of geosynthetics, the need to consider any geotechnical aspect of a project holistically rather than in isolation, encourage out-of-the-box solutions and, most importantly, emphasise conservation of natural resources. This Paper is an abridged version of the IGC 2021 Annual Keynote Lecture, delivered by the Author.
