Hydraulic performance, wave loading and response of PBA revetments and their foundations / Hocine Oumeraci in European journal of environmental and civil engineering, Vol. 16 N° 8 (N° Spécial) (Septembre 2012)  

Public ISBD [article]  inEuropean journal of environmental and civil engineering > Vol. 16 N° 8 (N° Spécial) (Septembre 2012) . - pp. 953-980 Titre : Hydraulic performance, wave loading and response of PBA revetments and their foundations Type de document : texte imprimé Auteurs : Hocine Oumeraci, Auteur ; Tijl Staal, Auteur ; Saskia Pförtner, Auteur Année de publication : 2012 Article en page(s) : pp. 953-980 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : PBA revetments Wave reflection run-up/run-down Breaking waves impact loads Wave-induced pore pressure Transient soil liquefaction Résumé : Polyurethane bonded aggregate (PBA) revetments are highly porous structures made of crushed stones durably and elastically bonded by polyurethane (PU). Despite their advantages compared with conventional revetments and the experience available from more than 25 pilot projects, design formulae to predict their hydraulic performance, wave loading and response are still lacking. Therefore, the paper addresses the analysis of large-scale tests performed in the Large Wave Flume (GWK) of Hanover/Germany. The study aims at improving the understanding of the processes involved in the interaction between wave, revetment and foundation and at developing the missing design formulae for a broad range of wave conditions. The analysis of an observed failure due to transient soil liquefaction under regular waves is also described.
