Applications of geosynthetics for soil reinforcement

Abstract

This paper gives an overview of the main applications of geosynthetics in soil reinforcement. It provides a pointernal to other sources of information for those who are interested in this topic and wish to go deeper into it. After a short section dealing with geosynthetics terminology and development, some aspects of reinforcement properties and design are addressed. In the rest of the paper each main reinforcement application (roads and railways, foundations, embankments, steep slopes and retaining walls) is briefly described, together with the corresponding design procedures. The paper ends with some general requirements for construction with geosynthetics. Cet exposé décrit les applications principales des produits géosynthétiques dans le renforcement de sol. Il indique également d'autres sources d'information à ceux qui sont intéressés par ce sujet et désirent l'approfondir. Après une courte section consacrée à la technologie des géosynthétiques et à son développement, nous abordons certains aspects des propriétés et types de renforcement. Dans le reste de cet exposé, nous décrivons brièvement chaque application principale de renforcement (routes et chemins de fer, fondations, berges, talus abrupts et murs de soutènement) avec les procédures de conception correspondantes. Nous terminons en présentant quelques critères généraux pour la construction avec les produits géosynthétiques

The Impact of Embankments on the Geomorphic and Ecological Evolution of the Deltaic Landscape of the Indo-Bangladesh Sundarbans

“…Already established earthen walls pressurize the soft, compressible riverine soils and the collapsing tendency temporarily brings disastrous impacts on the livelihoods of the region. Geotextile as a state-of-the-art geosynthetic-reinforced structure is considered to be one of the useful and cost-effective environmental applications, especially for embankment management [56,57]. Geotextiles are flexible and permeable continuous sheets of woven, non-woven or knitted fibers or yarns.…”

Pull-Out Resistance of Sand-Geosynthetics Reinforcement

“…Geosynthetic is related to many functions and usages. According to Pinto [1] and Ennio et al [2] geosynthetics such as geotextiles and geogrids are broadly used as reinforcement materials and stabilization. The design of the reinforcement always related to the ultimate tensile strength of the geosynthetics and it depends on the materials itself.…”

Beams on extensible geosynthetics and stone-column-improved soil

“…In all of these studies, no ground improvement technique was adopted and therefore these may not be applicable for poor soils/soft soils. In view of this, several researchers have used different ground improvement techniques and proposed the analyses for infinite beams resting on such improved earth (Indraratna et al, 2007;Maheshwari and Viladkar, 2010;Maheshwari et al, 2004Maheshwari et al, , 2006Pinto, 2003).…”
