| 摘要： | Although engineers have developed numerous applications for geo-textiles, there are five major functions: separation, reinforcement, filtration, drainage and protection. The major geotextile classifications are woven, nonwoven and knitted. Generally, woven fabrics exhibit high tensile strength, high modulus and low elongation. Needlepunched nonwoven fabrics typically have high permeability as a result of high porosity and conformability because of their high elongation characteristics. Thermally spun, bonded, nonwoven fabrics typically have high modulus, compared to needlepunched nonwoven fabrics, and high conformability. Depending on the manufacturing process, knitted geotextiles can offer high tensile strength and elasticity. Geotextiles are available in a variety of structures and polymer compositions designed to meet a wide range of applications. It is important that all geotextiles be composed of strong, durable, chemically inert polymeric materials that are resistant to the effects of site-specific ground conditions, weather and aging. |
