土工织物应用在国外的治河、海岸以及水利工程中,已有二十多年的历史,国内应用仍处于试验研究的探索阶段。由于这种材料具有良好的过滤、隔离,补强、排水和型模等作用,以及施工简易,价格便宜等优点,故已引起国内、外的普遍重视。1983年在胜利水库大坝护坡维修工程设计中,提出了无纺布和有纺编织物各200m长的试验段,以工程化纤滤层代替 Geotextile used in foreign countries, coasts and water conservancy projects, more than 20 years of history, the domestic application is still in the exploratory stage of experimental research. Due to its advantages of filtration, isolation, reinforcement, drainage and mold-type, as well as the advantages of simple construction and low price, it has attracted widespread attention both at home and abroad. 1983 Shengli Reservoir dam slope protection engineering design, put forward the non-woven fabrics and woven fabrics 200m long test section, the engineering fiber filter layer instead
