摘要

非织造土工布已广泛用于过滤。本文通过室内试验对土工织物-土工织物体系的堵塞潜力进行了评估。采用ASTM改良的梯度比试验装置测定梯度比和土-梯度比。采用一种非织造土工布和土壤对排水系统进行了模拟。结果表明，由于堵塞机制的存在，梯度比和土-梯度比随时间增大。而所测试的土工布可以作为细含量为20%的土壤的过滤材料。

A study on soil-geotextile interaction using gradient ratio tests

Nonwoven geotextile have been widely used for filtration. In this paper, the clogging potential for a soil-geotextile system were assessed using laboratory tests. An ASTM modified gradient ratio test device was used to determine gradient ratio as well as soil-gradient ratio. One type of nonwoven geotextile and soil were used to simulate the conditions in drainage system. The obtained results indicate that the gradient ratio and soil-gradient ratio increases with time because of clogging mechanism. However, the tested geotextile can be used as fi lter for soil with fine content of 20%.

期刊介绍： Scientific Review Engineering and Environmental Sciences [Przegląd Naukowy Inżynieria i Kształtowanie Środowiska] covers broad area of knowledge and practice on fields such as: sustainable development, landscaping of non-urbanized lands, environmental engineering, construction projects engineering land management, protection and land reclamation, environmental impact of investments, ecology, hydrology and water management, ground-water monitoring and restoration, geotechnical engineering, meteorology and connecting subjects. Authors are welcome to submit theoretical and practice-oriented papers containing detailed case studies within above mentioned disciplines. However, theoretical papers should contain part with practical application of the theory presented. Papers (in Polish or English languages) are accepted for publication after obtaining positive opinions of two reviewers. Papers published elsewhere are not accepted.
