ABSTRACT: This paper presents shoring supports for a deep excavation within soft to firm silty clay near a railway in Toronto. The shoring system which consisted of caisson/soldier pile walls with tiebacks was monitored during excavation. The tieback testing and field monitoring results were reviewed and discussed. Back-analysis using a finite element program was carried out to evaluate the shoring wall performance. Recommendations for the design of shoring walls in the similar soil conditions are provided.
RÉSUMÉ: Cet article présente les parois délocalization pour une excavation profonde dans la argile limoneux doux au solide à proximité d'un chemin de fer à Toronto. Le système d'étaiement avec les murs embrasses de caissons/soldier ont été surveillés pendant l'excavation. Les résultats des embrasses essais et les surveillances de terrain ont été examinés et discutés. Rétro-analyse avec d'un programme d'éléments finis a été utilisé pour évaluer la performance du mur étayage. Cet article va fournir des recommandations pour la conception des parois délocalisationdans les conditions de sol similaires.
