Public ISBD [article]  inJournal of geotechnical and geoenvironmental engineering > Vol. 135 N° 5 (Mai 2009) . - pp. 690–696 Titre : Active earth pressure on retaining wall for c-ϕ soil backfill under seismic loading condition Type de document : texte imprimé Auteurs : Sanjay Kumar Shukla, Auteur ; Shrawan Kumar Gupta, Auteur ; Nagaratnam Sivakugan, Auteur Année de publication : 2009 Article en page(s) : pp. 690–696 Note générale : Geotechnical and geoenvironmental engineering Langues : Anglais (eng) Mots-clés : Backfills Earth pressure Earthquakes Retaining walls Seismic loads Résumé : This technical note describes the derivation of an analytical expression for the total active force on the retaining wall for c-ϕ soil backfill considering both the horizontal and vertical seismic coefficients. The results based on this expression are compared with those obtained from earlier analytical expressions for the active force for c-ϕ soil backfill under seismic conditions, and found to have a similar trend of variation. The parametric study shows that the inclination of the critical failure plane with the horizontal plane decreases with the increase in values of seismic coefficients; the decrease being more for their higher values. The total active force increases with the increase in value of horizontal seismic coefficient; while it decreases with the increase in value of vertical seismic coefficient except for a very high value of horizontal seismic coefficient. Design charts are presented for various combinations of horizontal and vertical seismic coefficients ( kh and kv ), and values of cohesion and angle of shearing resistance for estimating the total active force on the retaining wall for c-ϕ soil backfill for practical applications.
