USE OF GEOSYNTHETICS IN LOWLAND AREA

Abstract

This paper describes the use of geosynthetics in lowland area. Soft alluvial clay deposits in this area in 5m to 25m depth, where land subsidence occurs due to ground water pumping. As the countermeasure for differential settlement caused by soft deposit and land subsidence, geosynthetics have widely used in this lowland area. Eight case-studies are illustrated, in which prefabricated band-shaped drain, filter, polymer grid, and glass grid are used, and the results are discussed.
