一种新型隔盐阻水复合土工布材料性能研究

study on the performance of a new isolatiry salt andblocfing water composite geotextile waterials

本试验研究的一种新型隔盐阻水复合土工布材料,包括两层长丝机织复合土工布夹一层高密度聚乙烯土工膜,由此构成的合成纤维不透水性布状织物可作为路基工程中有效的隔断层材料。通过室内试验分析隔盐阻水复合土工布材料施工碾压前后各项参数指标,其结果表明:隔盐阻水复合土工布材料具有防渗、压路机碾压不破坏、造价低等优势,对盐渍土地区公路路基的治理不仅具有较好的经济效益和良好的社会效益,而且在公路、铁路、民航机场跑道、输油管道等领域均具有广阔的应用前景。

A new type of salt and water barrier composite geotextile material includes two layers of filament woven composite geotextile sandwiching a layer of high-density polyethylene geomembrane,thus constituting a synthetic fiber impermeable cloth-like fabric can be used as an effective barrier layer material in road base engineering.Through the indoor test on the construction of salt and water barrier composite geotextile materials before and after rolling index research,the results show that:salt and water barrier composite geotextile materials,with anti-seepage,resistance to roller rolling does not destroy,low cost and other advantages,the treatment of highway roadbed in saline soil areas not only has a good economic and social benefits,and in the highway,railroad,civil aviation airport runway,oil pipelines and other fields have a broad range of applications.
