一、发展概况土工织物作为一种新型的工程材料,在国内外已引起工程界的注意;它以其强高、弹性好、耐磨、滤水、不易霉烂、经济等优点,而在土木工程中得到很好的应用。在国外,土工织物在治河工程、海岸及水利工程中的应用已有20多年的历史,1958年美国首次在佛罗里达州大西洋海岸的护岸中用土工织物滤层代替传统的砂砾石滤层;法国于1970年开始将其应用于土坝和其它水利工程中。近年来,在铁路、交通、水利等部门的土木工程中也得到越来越广泛的应用。据不完全统计,1980年全世界土工织物消费
First, the development of Geotextiles as a new type of engineering materials, at home and abroad have attracted the attention of the engineering; it is its high strength, good elasticity, wear resistance, water, not easy rotten, economic advantages, while in civil engineering In the very good application. Abroad, geotextiles in the river project, coast and water conservancy project has been in use for more than 20 years. In 1958, for the first time, the United States replaced the traditional sand and gravel filter layer with geotextile filter layer in the revetment on the Atlantic coast of Florida. France Since 1970, it has been applied to earth dam and other water conservancy projects. In recent years, railway, traffic, water conservancy and other departments of civil engineering has also been more widely used. According to incomplete statistics, in 1980 the world geotextile consumption
