Liquefaction potential of reinforced sand

Static liquefaction of fibre reinforced sand under monotonic loading

“…Fibre inclusions increase the number of cycles required to cause liquefaction during undrained loading (Noorany and Uzdavines, 1989;Maher and Woods, 1990;Krishnaswamy and Isaac, 1994). However, the data generated in these studies are only suitable for empirical interpretation.…”

Comparative study between needlepunched nonwoven geotextile structures made from flax and polyester fibres

“…The advantages of natural fibres are robust, superior strength/durability properties, good drapeability and biodegradability/environment friendliness but these fibres are biocompostable (Shah and Anand, 2002). Nevertheless, several researchers have reported the use of natural fibres including jute, coir, wood and bamboo in various applications such as soil erosion control, vertical drains, road bases, bank protection and slope stabilisation (Ahn et al, 2002;Datye and Gore, 1994;Kabina and Mrstina, 1987;Kaniraj and Rao, 1994;Krishnaswamy and Issac, 1994;Lee et al, 1994;Lekha and Kavitha, 2006;Lekha, 2004;Ranganathan, 1994;Rao et al, 2000;Sanyal and Chakraborty, 1994;Slater, 2003;Tan et al, 1993). Therefore, the overall objective of the present work is to compare and analyse the properties of needlepunched nonwoven geotextiles produced from flax and polyester fibres under the similar process conditions.…”

Cyclic behaviour of dry silty sand reinforced with a geotextile

“…Among such studies are Maher and Woods (1990), Das, 1994, Krishnaswamy andIsaac (1994), Vercueil et al (1997), Feng and Sutter (2000), Boominathan and Hari (2002), Shahnazari et al (2009), Moghaddas Tafreshi and Dawson (2009, 2012, Palmeira and Antunes (2010), Wang et al (2011), Sreedhar andKumar (2011), El Sawwaf andNazir (2012), Koseki (2012), and Srilatha et al (2013), which mostly concentrated on the evaluation of the dynamic behaviour of soils reinforced with plane elements and distributed fibers using the cyclic triaxial test, torsion shear tests, shaking table tests and resonant column tests. Ravi Shankar and Sitharam (2005) evaluated the dynamic properties of Ahmedabad sand at large strains by performing a strain controlled cyclic triaxial test on dry and saturated soil samples at medium to large shear strain levels.…”
