摘要：Geosynthetics is the term used to describe a range of generally polymeric products used to solve some civil engineering problems. The term is generally regarded to encompass eight main product categories: geotextiles, geogrids, geonets, geomembranes, geosynthetic clay liners, geofoam, geocells (cellular confinement) and geocomposites. The synthetic polymeric nature of these products makes them suitable for use in the ground where high levels of durability are required. Not only because, properly formulated, they can also be used in exposed applications. Geosynthetics are available in a wide range of forms and materials, each to suit a slightly different end use. These products have a wide range of applications and are currently used in many civil, geotechnical, transportation, geoenvironmental, hydraulic, and private development applications including roads, airfields, railroads, embankments, retaining structures, reservoirs, canals, dams, erosion control, sediment control, landfill liners, landfill covers, mining, aquaculture and agriculture. The paper presents basic aspects of geotextiles, drainage, geocomposite designissues and technical solutions of their use.
