全国第二届土工合成材料学术会于1989年10月11—15日在沈阳召开。来自水利水电、铁道、冶金和纺织等系统的代表计400余人,提交论文150余篇。土工合成材料造价低廉,施工简便,具有加筋、反滤、防渗、隔离等多种功能,其使用技术已在水利、铁路、公路、军工、建筑、矿冶等领域逐渐推广。 The second national geosynthetics academic conference was held in Shenyang from October 11th to 15th, 1989. More than 400 delegates from water conservancy, hydropower, railway, metallurgy and textile systems have submitted more than 150 papers. Geosynthetics are cheap in cost, simple in construction, and have many functions such as reinforcement, anti-filtration, seepage prevention, isolation, etc. Their use technologies have been gradually promoted in fields such as water conservancy, railways, highways, military industry, construction, mining and metallurgy.
