一、土工纤维布发展概况 土工纤维布在国外研究应用只有二十余年的历史。它用于土工结构中主要起分隔、渗滤及均布增强作用。因其效用明显、性能良好、价格低廉、运输及施工简便,所以发展迅速。现在许多国家已商品化生产各种规格牌号,大量地应用于铁路、公路、水利、建筑等部门,在 First, the development of geotextile cloth Geotextile cloth in foreign research and application of only twenty years of history. It is mainly used in geotechnical structures separated, percolation and uniform distribution enhancement. Because of its obvious effect, good performance, low prices, transportation and construction is simple, so the rapid development. Now many countries have commercialized a variety of grades, widely used in railway, highway, water conservancy, construction and other departments in
