Large scale field tests on geogrid-reinforced granular fill underlain by clay soil

Mitigating the bridge end bump problem: A case study of a new approach slab system with geosynthetic reinforced soil foundation

“…Meanwhile, extensive experimental studies, including smallscale laboratory model tests and large-scale field tests, were conducted on geosynthetic reinforced soils by the authors in several research studies (Chen, 2007;Chen et al, 2007Chen et al, , 2009Sharma et al, 2009;Abu-Farsakh et al, 2007, 2008Chen and Abu-Farsakh, 2015) and also by other researchers around the world (e.g., Binquet and Lee, 1975;Huang and Tatsuoka, 1990;Adams and Collin, 1997;Tafreshi and Dawson, 2010;Bai et al, 2013;Demir et al, 2013;Chakraborty andKumar 2014, Miao et al, 2014;Naeini and Gholampoor, 2015). The influences of different variables and parameters contributing to the improved performance of reinforced soil foundation (RSF) were examined in these tests.…”

Experimental and numerical studies on protection of buried pipelines and underground utilities using geocells

“…These reinforcements increase the overall performance of the foundation bed by increasing the load carrying capacity and reducing the settlement. Many researchers have studied the beneficial effect of the geosynthetic reinforcements in various geotechnical applications (Indraratna et al, 2010;Rowe and Taechakumthorn, 2011;Demir et al, 2013;Bai et al, 2013;Almeida et al, 2014 etc.). However, the use of geosynthetic reinforcement to protect buried pipes and underground utilities is relatively a new concept.…”

Effects of aspect ratio of footings on bearing capacity for geogrid-reinforced sand over soft soil

“…Natural river sand is the most common granular material used for this purpose in India. Studies have also been conducted to evaluate the improvement of bearing capacity for circular footings resting on reinforced sand-soft soil systems (Som and Sahu 1999;Alawaji 2001;Dash et al 2003;Deb et al 2011;Demir et al 2013). Many experimental studies have also been conducted to determine the bearing capacity of strip footings resting on sand layers of limited thickness over soft soil (weak clay) containing geosynthetic reinforcement (geotextiles or geogrid) at the interface (Gourc et al 1982;Das 1989;Dembicki and Alenowicz 1990;Alenowicz and Dembicki 1991;Khing et al 1994;Lee et al 1999).…”
