20.500.12556/DiRROS-20213 Changes of permeability of nonwoven geotextiles due to clogging and cyclic water flow in laboratory conditions The use of geotextile filters has been a common application in geo-environmental and geotechnical engineering for decades. The purpose of the present paper is to assess the influence of artificial physical clogging and cyclic water flow on the water permeability characteristics of nonwoven geotextiles used commonly in filter and drainage systems. Despite many studies examining the behavior of soil-geosynthetics, the mechanism of physical clogging is not fully understood yet and remains incompletely defined. Artificial clogging and cyclic water flow tests have been conducted according to a procedure created by the authors. Three nonwoven geotextiles and silty sand were employed in the test series. Hydraulic properties of the tested geosynthetics were determined according to the ISO standard. Filter design criteria are also discussed. The paper also presents the changes of water permeability characteristics due to clogging and cyclic water flow. The results show significant decrease of water permeability coefficients of the tested nonwoven geotextiles after artificial clogging and under cyclic water flow. Furthermore, the clogging mechanism was observed and confirmed by three-dimensional computed tomography. nonwoven geotextile clogging cyclic flow permeability soil netkan geotekstil zablatenje ciklični tok vodoprepustnost zemljina true false true Molecular Diversity Preservation International - MDPI Angleški jezik Slovenski jezik Molecular Diversity Preservation International - MDPI Neznano 2024-08-14 13:44:32 2024-08-14 13:50:34 2024-08-16 03:57:31 0000-00-00 00:00:00 2017 0 0 str. 1-15 iss. 9 Vol. 9 Sep. 2017 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2017-09-01 624 2073-4441 10.3390/w9090660 2322023 http://www.mdpi.com/2073-4441/9/9/660 Odprti dostop 1 d6ac27a2-5a21-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28300 RAZ_Miszkowska_Anna_2017.pdf RAZ_Miszkowska_Anna_2017.pdf 1 02F118A49DFACC842C34594AF0B6DD7F 2bca0f3f2d9524cbc041049c21d26e5c09c0fff5e71d805decccdbd6758080dd a248aab2-5a22-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28301 Zavod za gradbeništvo Slovenije 0 0 0
