Practical Applications of Various Geosynthetics in Korea

Prof. Eun Chul Shin Incheon National University, Korea
Past President, Korean Geosynthetics Society

He was born in Korea and graduated from Chungbuk National University in Korea. He obtained his M.S. degree from the University of Colorado at Boulder, USA in 1987 and a Ph.D degree from the Southern Illinois University at Carbondale, USA in 1994. Since graduation, he has been teaching geotechnical engineering at the Incheon National University, Korea, where he obtained a full professorship in 2005 and has served as dean of the Urban Science Collage until 2016. He is a Director of Creative Educational Program for Future City Design which is supported by the Ministry of Education in Korea. Now, he is a Vice President of ISSMGE for Asia(2017-2021). Prof. Shin’s field of specialization is geosynthetics, geotechnical, geo-environmental engineering, shallow foundation and ground improvement. He has published 5 books on the geotechnical, geo-environmental and civil engineering related subjects as well as more than 100 journal papers and 150 conference papers. Currently he is an editorial board member of J. of Geotechnical Engineering, and J. of Geological and Geotechnical Engineering. He has been an Editor of 4 conference proceedings for international conferences.


In the past half century since the late 1960s, geosynthetics have been widely used for the reinforced earth walls, ground improvement, slope protection, sea dike and shore protection, sanitary landfill, road and airport runway, and tunnel. The Korean Peninsula has 75% of land covered by the mountain and three sides of land are facing with the sea. Therefore, the availability of land for the use of residential area as well as industrial complex are quite limited. In this regard, geosynthetics are very useful material to extend the effective use of existing land with the slight modification of ground level and also soft ground improvement. Geosynthetics are excellent construction material when they are used with proper design and construction methodology, and quality control. The first part of this paper describes about the development the reinforcement earth technology in both old days and modern times. The second part of this paper presents various ground improvement technics with utilizing geosynthetics in the land reclamation project. The latter part of this paper presents about slope protection, and sea dike as well as shore protection. Finally, geosynthetics applications in the constructions of sanitary landfill site, road and airport runways, and water proof work for tunnel construction works are described with the field case studies.
